This will help for those who aren't too sure who/how many regs you should avoid.
Here guys this was a thread by CJ Saunders showing how much playing with other Regs affect your roi. The spread sheet was caculated for the 16$ at Pstars. Just changed the numbers for your buy-in if you like.
Basically, it says for a 9 man:
Summary, for 9-seater SNGs
Cost of a good regular (12% ROI) -2.80%
Cost of an average regular (6% ROI) -1.80%
Cost of a barely winning player (2% ROI) -1.20%
Cost of break Even player -0.92%
Summary, for 6-seater SNGs
Cost of a good regular (12% ROI) -4.50%
Cost of an average regular (6% ROI) -2.80%
Cost of a barely winning player (2% ROI) -2.00%

You must substract those numbers from your "base" Roi. It's your Roi if you were only playing against losing/ break even players. Also remember the Rois of the players are based on their "based Roi" so be generous as well.
Just play around with the spreadsheet, it encourages me to table select =D and hopefully others too. So **** OFF my tables at Full Tilt please and stop regging over me.

and I'll do the same!
