When P.Cell and Vegeta started fighting, in the beginning, Vegeta could put up a fight, and Sixteen even said that Vegeta was stronger. Then Vegeta was like, 'You're not taking this seriously.' And he prompted Cell to get serious. So I think that the power Cell showed when he tanked Vegeta's kick and then sent him far away was greater than his warm up power.
Is it possible that the power he initially used against Goku was the same power Vegeta fought evenly against? Come to think of it, Vegeta was WTFed when Cell tanked his kick, whereas he was not impressed during the warm up stage of Goku's and Cell's fight.
