When you sailed in those other classes... (and according to your report... did quite well) YOU set the benchmark for that class of boat! Your winning on time against all of the other top sailors racing established the benchmarks.

So... unless you see the rating drifting slower... for these other older classes... you can't complain.

Now for a new design... the rating gets faster over time. If you are the only one racing the boat... you are essentially setting a personal handicap. But when others contribute to the data set the system will approximate the boats ability versus the other boats.

If you compare your portsmouth rating to the texel or schrs measurement rating and find that you are significantly faster then under those system... you may have a complaint. (the measurement systems have their own blind spots... see schrs debate so the bottom line is that no system is infallible or perfect)

In comparing boats that I know sailed by the nut on the tiller that I know... I don't see real differences between rating systems (The F16 has been slow to drop to the Texel or SCHR rating though. The means to get a rating are very different but the end results have seemed to work out (with a few exceptions... )

Take a look at the Statue of liberty race or texel race.

The top of the fleet go racing a lot and finish in the top 1o in the national events. The boat classes are very different. Nacra 20's, Hobie 16's and HF18's.
