Your question is _bass-ackward_ in it's phrasing.  It should be "who would not
believe that Frans has spent more time testing with ponder=off than bob has,
so that it isn't a surprise that fritz probably does a better job of allocating
time in that mode than crafty does?"

_that_ is the point.  Not that I am better with ponder=on.  That I am _worse_
with ponder = off.  How hard is that to understand???
