Depends on the stakes you're playing.
You can 4 table high stakes and make a good return but in micros, it's going to be much smaller obviously. At micros though, volume is key to making a good profit, because players are bad enough you can get away mass tabling just using a HUD and playing a solid game. Of course though, your middle/end has to be good as this is where the profits come from, playing a tight game whilst multi tabling might make you a winner at micros ,but it will certainly limit your profits. If your end game isn't up to scratch you would probably be best playing less tables or even some hyper turbos, so you can get used to all the late stage plays a lot. A LAG approach, stealing and re stealing is key to bigger profits success in SnG's towards the later stages.
For earning more profits in MTT' SnG's in particular, An example is, you find a lot of regs even at micros, all have a solid tight game and are winners in the early/middle stages but their end game is just terrible. Of course they run deep sometimes through just picking up hands or spots but they will play way to tight, their calling and shoving ranges consist of value hands only. They understand stealing, but are very tight with their calling ranges, so if they are opening CO/BTN you can 3B shove them quite wide and expect them to fold hands they shouldn't be. They rarely adjust to your 3betting range will even fold hands as good as 55-99 to 3B shoves for 20bb or even AT/AJ/AQ. To be more successful than these players and have bigger profits is to exploit their tight game. Another example is; exploiting the good LAG who profits better than your average winning tight reg; he opens MP/CO with a wide range, you should be 3B shoving an even wider range with 15-20bb vs the LAG's.
If I grind SnG's I usually play around 10, playing 1-4 just doesn't seem worth it in general unless I'm doing something else.
