Not much I expect. The strength of the higher plies are mostly seen in
specific situations where the look-ahead is important. It is more a
question of reliability than overall strength. 64 points certainly
won't be enough to determine the difference with any confidence. The
best approach is probably to let  0ply play 0ply for a long money
session. Have supremo analyse the games for both players, and then
rollout any disagreements.  Then you'll have error rates to compare
for the two playing strengths.
