This is now time to start figuring out how to do the full test with a mask.
I've seen a lot of various stuff and if you have a ring of something that
looks kind of like a ring of a depression or raised at one area, you are
probably doing a very regular stroke on an improperly pressed lap.  The
other thing is that you may have a rolled edge or even be near the
parabolic condition.  You won't be able to tell exactly what you have until
you take some measurements of what the ROC of the various zones are. Bob
