At tables with frequent limping I'll see as much as 30% - 35%. However this is incredibly loose at a table with frequent preflop raising, which is probably where most folks who responded are coming from.

At micro NL tables I would expect your % to be much higher than at a table with more folks who know what they are doing.

Also, keep in mind that this must be talking about ring games. To talk about flops seen % in a SnG is pretty much pointless because of the fact that the game gets short handed as you move on.

I finished a SnG last night, took 2nd. I looked at my stats when it was over, and my flops seen was 70%. That's because 3 players busted out before the 30th hand. 3 more players were out before 80. It was heads up play for 60% of the hands dealt. So naturally the flops seen is going to be huge, even though for the first 50 hands my flops seen was only something like 25%.
