Re: [ATM] Figuring nightmare I need your help

good with a nice polishing movement. Stroke is chordal with the center
of the lap almost on the high zone. Overlap over edge is 2 inches.
Overhang on the length of the stroke is 2 inches. I did 15 minutes good
solid polishing and I have deepened the curve even more. Foucault

Sounds like you are working down the outer zones. When you do so, the
edge's Radius of Curvature lengthens, which increases parabolization. When
you analyze the 'high point' of the zone, you usually find that the best
place to attack is just inside this point. And, to keep 'contact' with the
center, you want to add in a lot of strokes towards the center.
