You're welcome, I hope it helps. Remember, this is my take on
figuring, and there are many ways to get to a finished mirror.

If the two five-zone masks have zones that overlap each other, that's
a good thing. A 2x or 3x scope will help quite a bit.
Please keep us updated on your progress. If you're enjoying the
figuring process, I encourage you work on the outer zones' correction.
Correcting the center is easier and can be done after the outer ones
are close.
