This corresponded pretty well with Betza's statement. Classical Pawn odds
(averaged over colors) deleting the f-pawn caused a 68% advantage in
Fairy-Max. The first-move advantage there was about 53%. (Probably a bit
smaller than in human games, because Fairy-Max is pretty stupid in the
opening, playing with a pretty strong randomizer there to provide game
diversity.)
So the difference between playing white or black ('1 tempo') is 6% The
difference between pawn ods and standard setup is 18%, i.e. 3 times
larger.
Note that it is quite difficult to be more precise: to determine win rate
with 0.5%-point accuracy already requires some 10,000 games.
