Hi Charles

Polish gently with no pressure for another two hours. Don't wet the lap
down too much with cerium, let the drag build up and polish slowly and
gently. Then have a look at your ronchi lines again at the end of the
two hours.
The TDE may simply be there because you are not polished out to the
edge, the same applies to the wiggly lines.
Your test has told you that there is no massive hole in the center, so I
quote the wise words of the ATM cabal (which does not exist and I am not
a member)...
