Set the points to maximum.

Buy the force you deem to be "comfortable" for the map size, and your style of play, and note how much it costs. Repeat the buy a few times with minor variants. Eventually, you will have your answer.

Now, set your points size to your benchmark, given map size, era, and posture (delaying, defending, meeter, advancing, assaulting).

Naturally - your preferred style of play and army will have an effect on this. You will have different results if you like to play VC or similar than if you like to play the IDF...

If your force walks - you will want a smaller map, or longer games, to trudge across them on shanks pony. If you are playing "air cavalry" you will have an entirely different point of view.

So - you are really asking one of those "how long is a piece of string" type of questions that really cannot be answered by some simplistic formulaic approach. Too many variables.
