This is my first year shooting a sight with a level. Initially, i had to make a significant effort to get the bubble level when i started in June. However, I now am drawing and the bubble is level because I've gotten used to holding it in the level position. I think it is a very useful tool because i have seen a significant increase in my horizontal accuracy by not having to worry about torquing it anymore. This was a problem I had with my previous bow and sight.
