These are not angles which I could possibly guesstimate visually, not easily at least. Someone has ONE job, to put a sticker on straight and couldnt get it right? It is an interesting question if there is a different tightening sequence, which uses a torque value for the first three steps, and just one angle for the final step, which would give the same bolt loading tension, but thats probably not an experiment that Id be looking to perform.
