BurnHard (sounds like a [H]ard|OCP name), there were many teams and members such as Morphy375 and Hoogie who did not use optimized clients and it would be unfair to them to reset the stats. I don't often mention my credits because some of them were done with optimization. The Dutch Power Cows and teams like TSC Russia can easily catch up. Some of the complaints from the hard core optimizers indicate that some of them have left already.

It would be possible for the stats sites to produce stats tables for before and after optimization.
