You would be better off taking the SCHRS tables and the Texel Tables and deciding what you want to set the DPN to...relative to your fleet.
This way... the fleet and the nacra owner can hunt you down and bitch... They will buy you many many more beers this way... If all you can tell them is ... well.... I looked it up on US Sailing.... No beer for you.

I have tried to get them to post it for a year and a half now and gave up dealing with them. I am thinking about switiching to SCHRS. They have ratings for production foiling boats and will return emails. I support switching to SCHRS for the FL300.

They are NOT going to be able to publish a PN number for a boat without a one design fleet actively racing in handicap buoys races. They need valid data and the reality is that the US does not generate it. It is a conservative position. Back in the day.... you would have had to prove that you at least 5 or 10 boats actively racing handicap and OD just to get a provisional rating published in the table. Two boats in the country are not a fleet....
There are very good reasons for this level of rigor.... It stops a rating that is essentially a personal handicap from substituting for the boat class.
Yes its a change from the Darline Hobock era and sailors have to take this into account when they adopt the system.
In portsmouth... it was an honor system that bound each owner to saying that their boat was a completely class legal XXX.
SCHRS and Texel can also operate on the honor system... AND it can also use individual rating certificates for Stock OD, One offs or highly modified OD boats. It's up the OA to spell it out in the NOR what standard is in play.

Otherwise known as malicious compliance. It is the responsibility of the committee to recognize the issues with the system and develop an action plan to address those issues. Maybe the committee is concerned USSailing will invite them to leave if they color outside the lines. No that can't be it that would be crazy talk.

People Volunteer to do the job....(it is thankless) When you look at US situation with respect to new cat designs... plus all of the modifications to one design boats and the very very small number of qualified buoy races that give you data... You have to make a decision. Does it work? Is it transparent? is it fair?
How far can you stretch the rules of the PN system?...
We have been making **** up for years AND... no one design fleet wants to take on getting data on their class relative to the yardstick boats. So.. Do you continue just making up new ratings.... AND wind adjustments.... just because you take a SCHRS rating and now GUESS what the US dpn rating should be is not a solution to the problem.
If the OA wants to do that... nothing will stop them.... just don't ask the US PN committee to participate in the flim flam to cover your butt.. You don't get the seal of approval when you want to race your N17 against an F18 fleet.
So... It is quite responsible to say.. .. ... Nah... it is better to preserved the rating tables for the boats (dinghies and cats) that data exist for. Clubs can use the data and pn system as designed... or they can change and make up their own table or pick a different system.
I have been telling you that the system for cats was BROKEN... not repairable and cat fleets should move on for over 5 years.
ITS TIME TO MOVE ON!
The PN committee is just preserving the integrity of the tables as designed.

What are you talking about!? Nobody cares about the USSailing seal of approval! Just because it's on the USSailing site doesn't give it any more cred than another handicap system. I kinda doubt anyone (except me, I'm a bit slow) is asking the DPN committee to do anything because we learned years ago the answer is always no and there will be no action taken. And the whopper of them all..."The PN committee is just preserving the integrity of the tables as designed." did you really type that with a straight face Mark? Come on, you can tell me we are buddies.

I think we're ignoring the possibility that nobody since Darlene has been able to run the math required to update the tables even if there was data to work with....hence the need for some of the guestimation.

the old boats that have ratings with tons of data behind them will not change. You only have to run the program for new boats... and you have no data..
So... until you have a data set of 25 races with a fleet of un rated boats racing a fleet of yardsticks...... not a problem.
(I think they actually can run the program... they just can't modify the code or want to rewrite the thing for the 21st century.)

which boats are considered "yardsticks"? And what if that boat's design changes (as part of an OD rule, etc.)? Say the F18 is the "yardstick" and they allow a modified sailplan as part of their OD rule... or a carbon stick. If either of these change the sailing characteristics (speed, angles, etc) wouldn't it move the entire PHRF table? I think there was a blog about this issue discussing the Farr 40 along with Time on Distance vs. Time on Time systems. Being relegated to PHRF myself (not a fan, but not sure I can convince anyone of the merits of another system) and rarely racing OD events, which system best combines both monohull and multihull fleets? I'm not even going to touch foilers at this point because I doubt I'd see a Moth, G4 or N17 anywhere I sail... I think in my PHRF area I rate about the same as a Melges 24 and a Hobie 16 non-spin. Which seems a little odd?

(I think they actually can run the program... they just can't modify the code or want to rewrite the thing for the 21st century.) It matters because if anyone puts in the effort to collect data that can't be processed they would be wasting their time. In the bigger sense, if the numbers are able to still be compiled then it would be nice to know what the committee feels is needed in order to update numbers or assign new numbers so the system can remain relevant to our sport. If they are fixed and unchangeable then it is more motivation to start looking at something like SCHRS that can adapt as our sport changes. There IS data available and the statistics will work on a relatively small sample size because it's weighted. I could probably dig back into three or four years of EMSA F16/F18/Acat single fleet handicap racing and provide a dozen regattas of data but I seriously don't think anyone since Jamie/Darlene has had a chance of processing it. I have a Fortran background and took a stab at understand it a long time ago but the statistics are really advanced and I concluded that I needed more of a statistics background (or the time to gain the knowledge) to be able to modify it in any meaningful/reliable way.

Posts: 5,590 Naples, FL | Jake, if I understand what you and others are saying is that the DP-N system is not being actively managed since the passing of Darlene's era?
If this is indeed the case, is there a more actively managed handicap system? I would suspect if there isn't much activity on the DP-N system (or no one knows how to update it) it will eventually prove to be of little use as boats/designs evolve. Even strict OD boats often allow some changes (maybe not in Star or Etchells..)?

Posts: 12,310 South Carolina | Jake, if I understand what you and others are saying is that the DP-N system is not being actively managed since the passing of Darlene's era? I don't have any factual information about whether or not that is a true statement. I do know that the system is very specialized and when I was involved, just before Darlene's passing, there was not anybody else able to run it although others had tried to pick it up and take that off Darlene. Jamie Diamond got involved at some point but I'm not sure he got it into a workable fashion either - I think he too had intended to make some modifications to it. However, I'm not clear whether Jamie was trying to just run it or modify it. I looked at it for a brief period and quickly learned that it was over my head in trying to modify it but I never tried to compile it as it was. The Fortran compiler was expensive at the time but it looks like you can get free compilers now. Darlene eventually took it back up in a limited fashion. I do not know of anyone that has actually compiled numbers using the actual system since Darlene but I have not been involved in several years. The software (Fortran) is tricky to run and requires a good deal of specialization with old programming / compiling software. My experience with Fortran originated in the time when it was running on IBM mainframes and you would interface with a command line green monochrome terminal station and had to schedule compiling time with the university. Someone on the committee today may well be able to compile the software and statistics as it stands but it's not something that just anyone could pick up and run with. It's definitely not an excel spreadsheet. ;-)

I just draw the line at completely fabricating numbers, geesh! Please try to pay closer attention it’s not the first time I’ve said this. Because there is NO integrity with the DPN system the fact it is USSailing sanctioned means nothing, you only have to read your own words to see that statement is true. Of course you support USSailing telling me or anyone else to go pound sand, that’s kinda your thing. Only you would tell someone in the sailing community who you pretend to represent to piss off. This position invites the community to move on without USSailing. I’ll stop whining when you stop being a sock puppet for USSailing. No that's not true, I'll stop whining when I stop caring.

The fact that most of you refuse to join, then publicly rant about no support doesn't help your case.
No one, and I mean absolutely no one, at US Sailing cares if you use a different system.
We've had these debates for eons here. A standard system is necessary for credibility. No one has crunched numbers to prove that there is a better system.
If one of the other systems is better to use, and has the support of the fleet, I will fully support it as the MHC chair.
Mike We have (I have personally), on multiple occasions, compared the systems with number crunching. Regardless, it's all handicap racing - it's never going to be perfect. It's a comparison of "worse" or "less worse".
