Interesting notes on the F-22's performance vs contract requirements:
http://www.f-16.net/news_article3275.html
Most interesting, is the "vs a Mig-29/Su-27"----the F-22 is apparently worth (in a fight) 10 F-35s. So much for the JSF being "90% of the performance for half the cost". (and now costs 1/3 more than the F-22) (of course, this is one of those press releases that's really more of an ad, so...)
