"opening up" at uNL = drop in bb/100?

[phydaux]

So far in my climb through the micros I've played a fairly consistant ABC tight-aggressive game with stats of 15/9/3. This style fit my personality, and I had great results with a win rate of >8PTBB/100 over 6+ months.

However, I've sort of looked at that as an unsustainable style that wouldn't work for me once I got out of the micros. I'd be too predictable and too exploitable by aware, thinking opponents.

So, keeping in mind I'm still only playing 25NL, for the last two months I've been exparamenting with a slightly more loose and slightly more aggressive style. Over the last two months I've run at 18/12/3. I'm still comfortable playing this style. However, my PTBB/100 has been cut in half.

It seems all I've done by "opening up my ranges" is I've added more varience to my results.

I can think of three reasons why I might have had the results I've had:

1) Everyone playing under 100NL is a chump, and 15/9/3 actually was a more optimum style.

2) My style change has done nothing because >8PTBB/100 was too high to be sustainable for any length of time, and all that has happened is my win rate has "corrected" to a more normal one.

3) The results of two months play is meaningless. Continue the exparament and we'll discuss it more in February.

Since I'm loking at grinding the micros for at least another year, is there a particular style I should be trying to emulate to max my earn? Should I be concerned with my recent drop in win rate?
