By the way, regarding the .5%-1% requirement for surveys, that's a load of poop. You need around 30-40 responses to start getting directional reads (as in, we could start saying "track cars tend to be more prone than street cars" or whatnot). You need around 500 responses to get reads at 95% confidence, and around 1000 responses to get reads at 97% confidence (have you ever noticed how all those consumer polls by Gallup and whatnot usually specify 3% margin of error with 1006 responses or something like that?). Still, these numbers require that the populations be unbiased and representative of the overall population, but we'd never get that here for 2 reasons:
1. People who've had RMS failure are more likely to respond than those who haven't.
2. Just the fact that you're on a forum for Boxster owners means several things about you that bias the group that would respond here.
Cool concept, but perhaps the only people who could do this survey the RIGHT way is Porsche, and the only people who could do it "almost right" is PCA, unless someone has a national list of Boxster owners floating around. :-)
