the degrree are not counted from your overlay podition thay are relaed to the screen…st las I brlieve it is so
dunno it it make sence but if you would repeat the same command the overlay will not turn …it doesnt count the degree together…
so if you start on -7.5 and want to turn it just 1.3 you had to do the math
-7.5 +1.3 = -6.2 and that should be the angle for the code
