I understand that, but it's very difficult to gauge that and get them equal, and not everybody builds them with air, for example here are 3 videos, all of them basically show them being built in a way that would leave no air, I think that was one of the points of adding the bleeder screws.
Here is Dustin Evans building emulsion before the bleeder caps

And here is Dustin building emulsion with the bleeder caps
What I am doing gives essentially the same result as what he is doing with the bleeder caps.

Both the videos with bleeder caps have the shafts being compressed, forcing the air then the rest of the oil out, then the screw put in. This leaves no air in the shock, if you want air you would draw the shaft out before putting the screw back, or you wouldn't have filled the shock fully initially. No air gives a more consistent zero rebound I think.
