Backstab bonuses fire from the wrong side because angles wrap around

A bonus for hitting an enemy from behind sounds easy until the enemy faces nearly straight right and the attacker stands just above it. The numbers say they are far apart, but they are not. This entry covers the angle comparison and how the bonus changes the hit chance.

Why this works

Directions live on a circle, where the end meets the start. Two directions are as far apart as the shorter way round, never the long way. Compare them that way and left, right and straight behind mean the same thing wherever the circle happens to be cut.

When not to use it

Skip it when the player cannot know where an enemy faces, for example when enemies turn too quickly to read or have no clear front. A bonus for something invisible feels random. Use a clear signal first, or reward positioning in another way.
