Angle of 3 fingers swipes

Regarding 3 finger swipes, it seems to me that it's too easy to trigger UP / DOWN gestures, and too hard to trigger LEFT / RIGHT gestures.

E.g. if I do ~45 degree angle swipe with 3 fingers, then it gets registered as 3 finger UP swipe. But if I do same ~45 degree angle swipe with 2 fingers, then it gets registered as 2 finger swipe RIGHT.
