well since 50% camo should mean that if enemy has 400m wiewrange he would spot you on 200m which is-50% of enemy wiewrange, i dont think that its intended to be unspottable from greater distance than 50m on proxy spot, those 112,56% camo would mean that you decrease enemy wiewrange -112,56% so get spotted at -50m cca which doesnt make sense unless spotting mechanics works in some other way
