After seeing a woman break 24 seconds and I think we can stop the discussion of "IF" the LZR suit is faster and start thinking "how much faster".
The previous line of suits (Fastskin and so on) were pretty similiar to a shaved swimmer. Sure - they do feel like they make you float, but overall the times seemed to move along "in line" with what I would expect to see in terms of improvements in the sport. If the previous suits would have been that much faster than shaving, you would have never seen people just using the legskins. By the way - for us Masters swimmers there was always the added benefit of keeping in all the "extra layers of skin".
So how much faster are the LZR suits ?
If I had to guess based on the results so far, I would say 0.25 to 0.30 per 50 and double that for the 100. I can see the Bernard going 48 low in the 100 and I can see Sullivan getting close or just breaking the 50 record. It makes sense that Libby Lenton would swim a 24.2 or so in the 50.
I think one of the top regular teams out there should do a test - you need a good amount of world class swimmers training together to be able to do a test. Here is the test I would propose:
8-10 swimmers
2 days of testing
4x50 on 10 minutes all out
Day 1 - swim 2 with a Fastskin2 followed by 2 with the LZR
Day 2 - swim 2 with the LZR followed by 2 with the Fastskin2
Get the averages of all 10 swimmers - maybe drop the high and low and there you go.
Why do the test ? I would HAVE to know. Swimming is a big part of your life and you just set a massive PR using this new technology - my very first question would be " How much was me and how much was the suit?"?

The LZR had a profound effect over a one month period since it was released. It's tough to argue I think that so much change has gone through other than the LZR being released over that 1 month period. Furthermore, the fact that many athletes who did not wear the LZR did not see the type of improvement swimmers who did wear it saw makes it even harder to argue it wasn't the LZR.
Because that isn't how science works. Correlation is not causation. You're assuming that the LZRs are the only thing that has changed.
When all you have is correlation, you need to make an effort to account for other variables that affect the result (either through directly controlling them, or measuring and modeling their effects, or choosing your observations carefully, none of which has been done to my knowledge) and you really ought to have a plausible mechanism for the effect.
If LZR legskins are really THAT MUCH better than FS-Pro legskins, I'd love to hear a plausible reason. No one here has offered one.
