Without trying to sound confrontational (sincerely) prove it!
I propose a test; Load two bog standard fixed spool reels with similar line, in similar fashion, then open the bail on one, slacken the the drag on the other and pull off the line. When the spools are empty, tighten drags/engage bails and retrieve the line by winding as normal. Do this in full repeatedly about 5 times and see how the line behaves.
