I think the whole scene battle and everything that went on went according to Sideous' plan. he killed the other three Jedi Masters in three strokes, then fought Windu long enough for Anakin to get into the position Sideous wanted him in. It was all as he foresaw IMO. I think if he wouldn't have wanted to get Anakin to turn at that moment he would have offed Windu after a bit of a fight. I think at that point he was the most powerful force user alive, slightly ahead of Yoda. Only Anakin had the potential to become more powerful in the force. then he got hacked to pieces and became more and more machine, which dampened his potential and merely left him the second more powerful force user alive. IMO based on Lucas' comments during audio commentary and my own fanboy thoughts.
