You don't have to know exactly, to the penny, but you should have a pretty close approximation what you are doing is worth, per number of trials or time.

Last year when my brother discovered the....I guess glitch...in the blackjack electronic machines, I wasn't sure exactly what it was worth. Being able to take a second action after you initially hit, isn't a standard rule anywhere (that I know of), so there was no looking it up in some set of unusual rules. I tried to figure out what the advantage would be myself and came up with a number, but I didn't trust that I wasn't missing something, so I asked around to a couple people like Wizard.

Funny thing was I got a couple very different numbers from two guys that I consider math experts. One was very close to what I had figured and one significantly higher. because time was an issue, we just started playing and 10 weeks later when we were finished actual results came in just about midway between the two numbers I was given. So who knows. At a couple hundred hands an hour we got in enough trials that variance shouldn't have been too big an issue. If it was something that was going to last a long time, I would have wanted a much more exact number as to what it was worth.

I am a little surprised to hear you say, machine players don't have such an exact number in regards to EV. That is not really my lane (at least yet), so I will take your word for it. But Blackjack APs know what their EV is per session.
