I enter total hands played and total money won. Then I have the spreadsheet calculate $$/hr and BBs/100 hands.
I have seperate formulas for 2 table play and 3 table play. I know I'll make more $$ /hr playing 3 tables but I want to know what my BB/100 hands is at 2 tables and 3 tables seperately to see if my win rate is dropping off by playing more tables.
I did that for quite a while. My win rate did drop off by playing 3 tables for a while so I went back to 2 tables. Im now able to play 3 tables at that same win rate as 2 tables, so I always play 3 now.
Someday I'll throw in 1 4th table and do the same thing.
