how to adjust to different kinds of tables

I play fixed limit holdem and am trying to figure out how to adjust -- more than I do -- to different kinds of tables that I tend to encounter way down at micro stakes. (By different "kinds" I mean the table averages for the overall tightness/passiveness of most of the players I'm facing at any given time at a table.)

I just ran a little report and found that over 20k hands, the tables I tend to lose the most at are the ones that are either loose preflop & then passive after, tight & passive, and finally loose & aggressive. My win rate is higher at tables that are more in the middle, & thus probably more predictable. I think this is mostly because I'm a newbie and tend to play somewhat mechanically, more by-the-book than I know I should. So here examples of the different overall playing styles at the kinds of tables I'm talking about. Chime in about how I should more or less be adjusting ... which is what I'm planning on doing from now on.

1) Loose/Passive tables: VP$P >= 30, PFR <= 5, AF <= 1.5 (the most common tables I come across, btw.)

2) Tight/Passive tables: VP$P >= 25, PFR <= 5, AF <= 1.5

3) Loose/Aggressive tables: VP$P >= 35, PFR >= 10, AF >= 3.0

These are just approximate, hypothetical stats -- just look for general strategies for how to adjust. Thanks!

20K hands isn't shit
especially for categorizing which tables are best

anyway, in fixed limit you can use a consistent PF strategy because opening too loose vs. fish is a preflop mistake, but you're swapping mistakes for their post-flop mistakes
likewise, tight players might fold their blinds more often even though they'll play post-flop more reasonably

and post-flop you should make adjustments that are based on players, not tables
