I think your %(of flops seen) is really going to vary on certain factors. Buy-in, aggression level of the table, what kind of players have position on you, what stage of the tournament you are at, and how you're running at the given moment. Certainly it could be too high (loose calls) or too low (missed playable hands)

But I'd suggest reviewing your HH and looking for both. You could be making both mistakes and have your % balance out.
