Percentage played of Postflop

I was hoping someone could tell me approximately how often a player should be seeing the flop,turn,river, and showdown. After about 2500 hands (which I understand is not a large enough sample to make solid conclusions), I reach each level the following percentage of total hands played:

22% flop (i follow the SSHE chart for starting hands)
11% turn
6% river
2% showdown

I seem to be playing a negative EV game, so I wonder if I'm playing my hands too far beyond the flop. Are there any established guidelines for how often one should see each level?

Sample is proabably too small to determine these stats, and WAY to small to determine any sort of win rate (need +100k hands).
Given that, pre-flop of 22% is decent maybe on the high side, but I don't think so, 50% flop fold is about right, but then you fold 66% (4% out of 6%) on the river which probably means you are folding too much on the river.

Better stats to look at are WSD% (went to show down) and W$SD (won $ at show down). WSD% should be around 30 and W$SD should be in the low to mid 50s, although it will depending on how you are running.

Remember it is important to show down in large pots, don't fold 20-1 river bets even if you think you are most likely beat.

While Miller says small stakes players go too far with hands, it is a generalization, so try to do what is right for each situation. Meaning don't think "oh bad players go too far with their hands, so I am going to be a good player and fold here and not make that mistake". Applying broad thought processes to the game is not going to be +EV.
