Introducing any sort of doubt significantly decreases your abilities to nail down your EV accurately.

This is why sklansky writes that he doesnt actually do any sort of EV calcs at the table, and theyre purely for learning purposes. Its just too hard to identify your edges that precisely in practice.
I think your logic is a little fuzzy here. If a poker bot calcs an edge of 1% with a 3% margin of error you should STILL TAKE THAT EDGE EVERY TIME. Because ON AVERAGE, YOU'LL HAVE AN EV OF +1%.

So when you are making an EV calculation, if you make an educated guess that you have a 3% edge but your margin of error is 10%, you should take that edge because in the long run, you'll gain money.

But the problem is a players margin of error isn't always even. Some people err towards calling, some towards folding. Which makes this even more complicated...
