NL 100...4 4 4 flop with lots of preflop action

[soah]

Showing profit on a hand that you raise with 16% of the time is not a very compelling argument in favor of raising it preflop. It would seem to indicate that limping is highly profitable.

And over the course of 100k hands, how often do you get dealt 99 UTG+1? A sample size of 50 is completely meaningless anyway.
