No data = no fix.
Some data = some fix.
Lots of folks would argue that some improvement is better than none, and most of us accept Portsmouth as an imperfect solution that takes marginal effort.
Personally, I'd have zero problems moving to a different system, but years of debating has resulted in zero support, and more importantly, zero volunteer base to make the sale and implement.
Arguably, today's Hobie 16s are at least somewhat faster than the old days, even 10 years ago. Incremental changes have been made to stiffen the platform, allow greater mast rake, and improve handling of running rigging to make adjustments and maneuvers easier. Since Portsmouth is based on performance and not strictly design, an excellent case can be made to update the number. Having said that, the difference probably isn't much, and we'll need a bunch of new data to make a dent in the existing pool.
