In the TYR lawsuit brief mentioned in the previous post, Mark Shubert is categorically quoted on page 8 - Line 6, stating that the Speedo LZR would give a swimmer a "2% advantage" over any other suit.
What does a "2% advantage" mean and how was that number quantified?
Will you finish all your races in a time that is 2% faster than ever before?
Does it mean that a Speedo Lzr is simply 2% more "slippery" or more hydrodynamic than any other suit on the market?
The math doesn't support it and there is no way that Mark Shubert was able to test a Tracer Light, Tracer Rise, blueseventy pointzero3, or an Arena Powerskin R-Evolution in a plume or wind tunnel.
Pieter van den Hoogenband's set a world record in the 100 LCM free at the Sydney games in a time of 47.84. If you then compare it to Alain Bernard's world record set at the European LCM Championships last month in a time of 47.50, that is not even a single percentage point faster but rather a 0.07% reduction. It's impressive but it is not 2%.
In the 50 free the time differential between Popov-2000 and Bernard-2008, we see a .98% reduction. Again, this is not a 2% differential. Michael Phelps dropped his 200 back time by the same percentage in just 4 years without a Speedo Lzr.
Shubert's 2% claim is an extraordinary one and it demands extraordinary proof.
