Here is the result from the "perverse" version of Beowulf, where I can change
pawn value to anything I want.  Of course, the results are reported in pawn
values that are not worth 100 centipawns.  Here is the personality file I used
for this analysis:

E:\programme\winboard\beowulf>type \pgn\winboard-engines\beowulf\personality.dat
115 ; person.pawn_score
0 ; person.use_delta

The default of 100 centipawns per pawn found it faster.
