Feedback-Bearing Line Missions

Please make the bearings on the line missions more forgiving. There’s too many times I have to restart a 20+ bearing mission because I’m missing a bearing by a centimeter. 
It’s extremely frustrating especially when you spend an hour doing a certain mission, getting better, and you have to restart because of a dumb line that you guys developed. 
The lines in the missions already make no sense but making the bearings hit box smaller than anything ever is very frustrating
