Lets see if we are talking about the same thing: There is a silver band on the mast, about 2-3 inches wide which on its upper side has a black band. The lower side of the silver band is practically at the same height as the mount of the mast rotator. So you say you get the luff of the main lower than the black band, to the lower side of the silver band ?? This is impossible for us, we can get the luff to the black band with 16:1 and at this position one has to crank really hard.
See for example:
This is about the toughest setup we can get.
