Winch question of feeding line

I have a basic winch question.

Is there anything special you can do when you have to winch at an angle where the tree you are using as the anchor is off to one side so the line feeds more uniformly rather than bunching up on one end?

Given that your pull drops with each layer you obviously want to keep the rope feeding the uniformly on the drum.

My first thought is you basically winch as much as you can assuming you are making progress...stop, unfeed the slack to get back to original rope out, feed back uniformly on the drum until the slack is gone, and then repeat process. The caveats are the position needs to be stack..does not slide back after slacking ..and loss of any momentum is not lost.
