I am not overly familar with the total strategy here as I am still at basic status (and from the way some people act here I'll probably stay that way) but I would offer the advice that 6,000 hands is not really a large enough sample size to get much of an overview.
However, it does seem that 11/7 is rather tight.
Are you blind stealing? (If the strategy you are using permits this)
Are you using implied odds to call raises with your low to low-medium pockets pairs? From the parts of the strategy I have read you are supposed to use the "Call 20 rule".
As an example:
You have $10 and you are in LP at a NL10 table.
Early positions fold.
A player in MP (also with $10) raises to $0.40, all players fold to you and you have 44.
To calculate whether or not you can call this raise using the call 20 rule means that you and the player that raised would need to have 20 x the original raise amount.
So .40c x 20 = $8.
Therefore you can call the bet and still follow the strategy that you are. If however you were sat with $6 or the raiser had $6 you must fold. If you don't hit the flop and the raiser leads into the clear move is then to fold. If you hit the flop, well I'm sure you know the rest.
Also, if the raiser doesn't lead into you and the flop comes with a few scare cards and you feel you can take it down should the raiser check to you, a nice amount is usualy 2/3rds of the pot.
Also, if there is a raise for examle of 4 X BB and someone else calls, I am not sure how your strategy works exactly but say you are sat with suited connectors of 4,5 or higher this would usually be a good place to call also.
If I am wrong and your strategy that you follow has it's own views on this then maybe you should follow that as last time I tried to help someone they were told to ignore me, which I found rather rude.
