Bug with drift and complaints with settings.

Im on a duel Sense ege controller and I decided to play zero zero. I know I would have drift at least a little bit I have constant drift to my dead right. I happen to put my controller on a 30 dead zone curve just to have it stop moving when I change my stuff yet I still have constant drift same speed even on 1 dead zone through the game. So how come when I do 30 dead zone on my controller I have constant drift one detection and one speed on 1 and 0 dead zone. So I decided to put my controller dead zone on 0 and only change it through the game. Yet still the same drift. But if my game dead zone is on 2 then I have nothing. Like zero drift at all not even a build up of less and less drift so I know my controller isn't messed up. Then I put my controller on 30 with 2 in-game dead zone. No drift. It's like the game is just deciding how much drift I will have for me? Also make it so yaw speed and pitch speed can go up to 1,000.
