I'm finding that 2 or 3 mistakes for stacks frequently result in negative sessions. Is the margin of error typically this small?

It can easily be this small.

A strong win rate is 10 PTBB/100 = 20 big blinds per 100 hands, or 0.2 big blinds per hand. That's a strong win rate. Make one mistake for your stack every 500 hands, and there goes your entire edge.

The strong win rate of 10 PTBB/100 includes getting stacked once in a while. The fish make so many mistakes for their stacks that I think you could overcome getting stacked once every 500 hands.

Of course you'll get stacked at least that often. I'm not talking about Sklansky FTOP mistakes. I'm talking making an error that, with sound ABC play (not omniscience), you shouldn't have made.

My point is just this: Over 500 hands you can expect, with a good win rate, to win only ~100BB. So it's very easy to throw away your entire average win for those 500 in one single boneheaded play. The edge IS that thin.

i agree, just would say the edge isnt that smal but the mistake is so big...
