I'm betting that you are referring to studies which show that you don't actually produce power pulling up on the pedal, but at most are partially unweighting it.
That's far from saying that in the real world you can't ride faster with your feat clipped in than you can with street shoes on platforms.
See post #34. I like Racer EX's anecdote better, though. He didn't even have good platforms OR good shoes and didn't being unclipped slow him down. I'm sure he would've been a LOT more comfortable and confident being clipped in or even just having good sneakers on good platforms.
