sorry for the late reply brobs, but I think you might have misinterpreted the point of the anglelerp feature
normally if you lerp two angles like
lerp(245,15,0.5), instead of going from 245 up to 15 crossing the 360/0 boundary, it would go backward down to 15
this let's you lerp the shortest route of 2 angles even if it jumps the 360/0 boundary.
now that it's solved I won't go back and figure out what you were trying to do in greater detail, unless you'd like me to
in which case...I will
