I'm about to pick up a second hand deathadder 3.5G to mod my wingman gaming mouse. There's a chance that I won't be able to mount the sensor so that it's at the same height off the mousepad as it would be in its original casing.

So I have two questions.

1: Suppose the lift off distance (LOD) is 1/4 inch. If the sensor is at 1/8 inch off surface, will it track perfectly? Or does the tracking quality vary as a function of how far the sensor is off the pad (obviously when it exceeds LOD it'll be non-existent, but I'm wondering whether it degrades gradually, or whether it functions perfectly until LOD threshold is reached). I've never really used an optical or laser mouse so have no experience to work with here.

2: Will I be able to change the LOD in the driver settings for this mouse? I'd like to be able to tune it such that it stops tracking as soon as the mouse lifts off. Having quaked with a ballmouse for 16 years, I'm not used to having any sort of LOD.
