Oh! What a strange way but should be considered!

I've never thought to control bias in that way. How do you determine the multiplier factor? I means, if monitor A is 10% smaller than monitor B, does that means we must makes movement in computer A 10% slower? Fine.... but we have a lot of other variables, did you simple makes everything less 10%? Or you adjust based on user experience and your instinct?
You have a very nice idea.
