Thanks Mirror god!!
Past few days, as a bit too busy [ or lazy

]to go back to #1200 and making a new pitch lap, I spent a few more hours with the pitch lap I am now using:
some ways to try to improve the rolled edge:
1. more frequent cold press for good contact
2. hands placed in the center of the glass, and not on the edges.
3. Keep movemnts horizontal and slow. Push ( and pull) the glass with whole body weight ( back straight, bend your knees and ankles). As in Tai Chi
4. 1/3 COC. Alternate Mirror on Top, and Tool on Top
5. stop the polishing after 10 to 15 minutes, and take a break of 5 to 10 minutes, not to let the glass and pitch to warm up

So far the rolled edge is much reduced. Still some turned down edge.
Next I am going to tackle the remaining turned down edge, and the hill in the center
thanks!!
