The idea isn't to play optimally, which is obviously not going to happen playing 6 tables, it's to play the number of tables which maximizes your overall hourly rate. If I can make $5 per hour, per table playing 6 at once, but only $7 per hour per table playing 4, I'd make more money playing 6 at once even though I'm not playing my best. I don't have exact numbers for SNGs in particular, but in ring games the added tables are definitely worth it.
