Casino & Player advantage = 0

I am learning to count the right way after years of half way counting.

It occurred to me that I do not know the point where the player and the house have the an equal expectation in the count.

If my IRC is -20 in a 6d strip game and +4 is my pivot where I know I have the advantage, at what count do I have an essentially even game?

I tried to figure this out and I determined that counts from -3 to +3 are pretty much 0.

Is this correct or am I over complicating/simplifying the problem?

Also if this is a stupid question feel free to educate me. profit before pride.

Thank you
