I dunno,Mace looked like he kicked ass pretty good & built up a sweat doing it.Yoda was stronger in the force probally because he'd been alive for 800 years training jedi & such.What got me a bit was that Dooku took out Obi-wan twice(Episode II & this one)pretty quick,while Anakin kicked Dooku's ass,cut his hands & head off & yet fighting Obi-wan took longer & he lost.
