Isn't this all getting a little over-complicated? If both tune and load controls are adjusted for maximum output at rated drive (~100 watts), there should be no arcing and performance should be nominal. If you want, add a little loading (clockwise) past peak output for better IMD performance. Once you're peaked, tape an index card behind the knobs and mark the settings for each band. You'll discover that on 80-20 meters, setting to the marks will be close enough, while on 20-10 a 2-second touch-up on the tune cap is all that's really needed.
