Yeah, after this fiasco that was my conclusion as well. Hopefully this will become less of an issue as more and more futures go electonic. I've found the slippage is so horrible in the pits in most cases that there's not even a good way to estimate it -- if I use the worst fills I'd never trade again. If I used the best fills it woefully underestimates the slippage.
