I am a bit surprised at your questions considering you claim to be a rigger.
The center of effort adjustment is = to about 30% of the mast head movement. i.e. mast tip movement 1 Ft. = center of effort is moved in the same direction 4" (= Makes a difference) granted if you have 200# load on the end of the tiller of weather helm you will need to move the center of effort more than a foot forward to balance the rig. Which is not easy just using the stick rake movement.

Lastly the loading of the vessel does have a great effect on the trim as well, Buoyancy and hydrodynamic centers of effort are moved forward or back depending on the loading. I am loaded mostly on the factory lines but I did have a heavy weather helm of 30#+ measured at the end of tiller with a batten less main. So I cut the foot down by 1 foot to 14'-0" and jacked the mast head forward about 4" and I am now near balanced +/-. and enjoy a 0 to 3# weather helm (My preference) (My wind vane also likes this preference)

P.S. I hate to say this, but you and Brian Toss both make me think twice before asking any rigger to do rigging for me. So far this thinking twice, has worked well for me and given me insite to look at what is being said, and not just believe blindly .
