when measuring sens in terms of cm/360, where do you start measuring from? what i mean is: i am a right-handed user. i keep the mouse near the left edge of the mousepad, get a ruler and start measuring. but does the measurement start from the location of the sensor at that point? or is it from left/right side of the mouse? i think measuring from the sensor position makes sense, but i figured i'll ask this silly question anyway.

also, can someone elaborate why it is measured as cm/360 and not cm/180? what i understand is this: some may say that 180 degrees is probably the amount you usually need to turn at most, so sens should be measured with this in mind. but it is measured by 360 degrees because that's the complete amount of crosshair movement on the horizontal plane. also, for some players/situations, after turning 180 degrees, if someone has to turn 180 degrees again, the mouse may not be picked up and reset it's position but rather continue moving it further from it's position until the required movement is complete. lastly, measuring in 360 degrees is the correct method to find the required amount of mousepad space, compared to 180 degrees.
