Weaker play at the 2 and 3 table sng's?

[Runner Runner]

I play the 20s and 30s and occaisonally play a 2 or 3 table sng's while I am playing a couple of 1 table ones. I have noticed that the play at these seems to be weaker then the play at the 1 table sng's. Anyone else experience this?

Also, since they take longer to play, how much weaker would the competition have to be to allow you to make the same amount of money over time. I am guessing that play would have to be quite a bit weaker, because the tournaments take quite a bit longer to finish. Still though, it's great getting heads up in these things, because you actually have a semi-deep stack and there is some play left rather then just push/fold.
