I am just wondering if there is any "ideal" placement to put my vanes and or feathers on the arrows?

In other words, how far from the the nock should I be putting them, I look at lots of pics and it seems to vary a great deal. I have always used 4" feathers and am trying out the Blazers next week. Just curious if there is any formula or rule of thumb for vane location on the shaft.

Thanks
