If Stefano Ghiorzo wins a two week
contest in the Diana, then he probably had won in an ASG-29, too.

I do not agree. Stefano is leading by just 2.3% over # 2 Leigh Wells
in an ASG29. I'm sure that the Diana-2 advantage over the contest has
been much more than just 2.3%. If he had been flying an ASG29, I am
convinced he would not be leading as the ASG29 suffers much more than
2.3% against the Diana-2.

Cockpit size may be a factor in the USA, but in the rest of the world,
most people are still reasonably sized.

I agree on that. Americans are over sized and need to consider that
more than anyone else. However, the American market is small compared
to the rest of the world anyway. It would be interesting to study
physical fitness Vs. placing at a World soaring contest. I can not
remember grossly overweight pilots ever placing in the top 3. I think
there is a correlation and cause and effect there. Sorry but I think
true.

Reichman wrote is his book that fitness is a very important element of
success in competition soaring.
