So... you think a single number system (IRC Texel, SCHRS) can describe ANY boats performance from 3 knots to 25 knots?

To do so... would mean all of the boat's in the fleet have a linear performance curve!

The rule could require a supercomputer to compute but the output... a single rating number, will be valid over a tiny range of conditions.

the USA Portsmouth recognizes this fact of life and generates 4 ratings... Texel generated two ratings bands.

The problem is RC compliance and sailor interest ... the folks who are doing the scoring run a handicap race once or twice a year... It is difficult for them to come up to speed with a 4 number rating system. In practice somebody learned a primative program years ago... So, they get that person to come back and score the regatta each year.. As far as I know... the ONLY scoring program that handles the full USPN Windspeed or Texel wind speed rating system is Sailwave. It is simple to use and works extremley well.. BUT, in my world, the yacht clubs use javascore which can handle a single number .... Unless I do the scoring.... We can only expect a single number rating score...

Coupled with general apathy on the part of sailors in requesting wind adjusted or team weight adjusted scoring.... we get what we get....
