Say you are playing with a simulated 1% EV and then decide you want to have a higher EV, so you increase your spread as necessary to allow for a 1.8% EV. On paper, the difference should be evident, but what I want to find out is if it is noticable in a practical sense? (Some may say, what does it matter whether you can feel a difference or not, that if you're getting the gain on paper then that's all that should matter. Correct, but I am curious).
I have been fortunate to be able to experience double digit EV in certain plays and this definitely was noticable. But how about smaller differences such as above: 0.8.

I know some AP's focus on how much they want to earn p/hr, then simply get the necessary bank and apply the correct spread and fire away. In which case maybe little consideration is given to their actual EV figure since win rate is their main focus.
