Post flop aggression - out of wack?

[RED FACE]

flop 2.53
turn 2.49
rive 3.56

ave. 2.66

Does the average seem ok for a fairly tight player?

I know these numbers don't take into consideration bets sizes just frequency but is it normal for flop and turn to be constant and river to be about 40% higher?

I wont be suprised to hear that the turn number is too high as I think I continue betting the turn with just 1 pair too often.

anyway, all comments welcome

Seems pretty low.
