I'm surprised that few people bother to read the README. Aleksi Elomaa (Monaco WRs with Lotus and Eagle), Phil Woodward (several WRs), and Elias Hirvonen (several WRs) got the patch for testing early on.
Didn't see a readme as I don't have the PATCH. You might have pointed out the talent listed above with out the attitude.
I usually have an 'attitude' when someone presents incorrect information as a fact (if you did not know, why did you claim no record holders have been asked to test it?).
Phil Woodward posted his comments on the 60fps thread at RSC. Aleksi (and many other testers) read this forum so he might be persuaded to post his impressions. Because some people take this issue so seriously, it is better that I won't post summaries of anyone's comments. Let them speak for themselves.
I don't think laptimes are as sacred as you imply. GPLshift allows faster shifting by reducing time spent in neutral, and yet the resulting laptimes are accepted as WRs. 60fps replays are identifiable as such, therefore WR laps can be kept separate if its considered necessary.
