Multi-tabling

One advantage of playing online is that one can play multiple tables at a time. I've never tried playing more than 3 tables at a time and I thought I should give it a try. I played 6 SnG's at the same time and it was very confusing for me. 

There were 2 9-player SnG's, 2 18-player SnG's and 2 27-player SnG's. I busted out early on the 18-player SnG's and the 27-player tables were not that good either. I finished 2nd and 3rd in the single table SnG's. I invested a total of $7.20 to paly these 6 tables and I got back $4.50. I lost $2.70 in this experiment and I don't plan on doing it again. I'll stick with playing a maximum of 3 tables.
