Outside of Phelps and the relay the times aren't getting smashed. Since 1996 you can track the progression of Olympic swimmers and you'll notice how much depth there is now compared to 1996. This helps explain the dramatic drop in time on the free relay. The suit and pool have a little to do with it.

I ordered a LZR racer and will test it out. If I drop a significant amount of time I'll let you guys know. Doubt that will happen though.
