Tight play wins the money? Pokertracker says not!

[donkeyradish]

Since pokertracker started 'autorating players' I wondered which of the profile types was winning the most $. My database has about 8000 hands in it, not a lot but this isn't about my own stats. Its about everyone elses.

Only rating players with 30+ hands played in my database, I have a wide spectrum of player types. Using the filter option I can see how each group does on the summary page.

The 4 groups who lose the money:

sLP-P (-8 BB per 100 hands)
sLA-P (-6 BB per 100 hands)
LA-P and LP-P (-5 BB per 100 hands)
Maniac (-1 BB per 100 hands)


Then there is a group who roughly break even
TP-P. LP-A, TA-P, TA-N

Now the surprising part
TA-A, the group I've been trying to emulate win 3BB/100
TP-A do about the same.
sLP-A win twice as much, near to 7BB/100 and
sLA-A win twice as much as that, 14BB/100!!

BUT streaks ahead are LA-A who win 22BB/100 hands !?!!?
Of all the LA-A players in my databse, 80% are winners.

These are aggressive players with a VP$IP averaging 45%?!?!

Pokertracker seems to be telling me:

Be aggressive, be very aggressive, and play one hand in every two! Can this be true? Surely not

I must be missing something obvious here. What is it??

(Ratings based on 8,000 hands involving 7-10 players at a mixture of limits, $0.5/$1 $1/$2 and $2/$4)
