Lately I have based my playing on time. I will play at night for 2 hrs 4 tabling. I just started with the whole time thing. No one told me to do it this way I just decided maybe it would work. Here is a typical night for me.
We can say 1 hr into my session my stacks look like this
25NL full tbl PP

Table 1: 27.80
Table 2 34.00
Table 3: 24.75
Table 4: 26.00

30 minutes later it may look like this.

Table1: 32.00
Table2: 24.00
Table3: 45.00
Table4: Reloaded 25.00

When I profit a certain amount should I just stop for the night? Or just play for 2 hrs during the weeknights? I am having a hard time with a correct way to profit and then maybe move tables, quit, or stay put. If I make a buy in for a 2 hr session which would be 50/bb per hr thats good right ? For instance, would it be ok to make 6.00 at each table and then quit? My variance is coming from stacking a person and then playing more aggressive because i have the chips and Iam more than likely picking on a smaller stack. So through my sessions Iam up and down and all around. Advice?
