Re: How Accurate Is Aggression Factor For Small Sample Sizes?
[ QUOTE ]
I would guess it is comparable to how accurate VPIP and pfr are over a small sample size

I disagree because with a small sample, VPIP and PFR are still primarily related to the 169 possible hands you can be dealt (for the most part), while post-flop aggression involves the added chance that you hit on the flop/turn/river, plus the need for your opponents to have hands hit also. I think there are many more variables affecting total aggression than VP$IP and PFR.
In other words, PFR and VP$IP are percents used in binomial distributions so we can calculate what we expect the distribution to look like even for small n. Post-flop aggression depends on your holdings (like PFR and VP$IP), but also depends on the flop (of which there are 19,600 possible outcomes), as well as your opponents style of play / their holdings.
