I got away from the feather to the nose business as for me it just fed in to some bad habits. I focus on my draw and settling into a solid back tension, allowing all else to follow that as I expand through the shot.
But, a good way to get the feather position correct is if you have an old arrow already fletched with the same cut of feather you will be using and, assuming the feathers are too far forward, begin making small cuts on the back end of the arrow (take the nock out first---ask me how I know) until the feather is in the position you want it. Like using a clicker the important thing is getting just the right position, so this is best done over a series of shooting sessions to confirm before you set up a dozen arrows.
Good luck with this!
