right...lets look at the evidence
from episode 2
"im grateful to be obi wans apprentice...he's as wise as master yoda and as powerful as master windu"
does this imply that windu is more powerful than yoda?
perhaps
palps beat yoda?...mace beats palps?...
lets look at what happened at the end of windu vs palps fight
palps is having the force lightning deflected into his face and he is saying
"i cant hold this much longer anakin...im too weak"...
anakin then gives windu the chop and palps suddenly changes to screaming
"power...UNLIMITED POWER"
chucks mace out the windu then stands up as if he has just slipped on a banana skin rather than having his face fried off
