Looks more to me like a flat center with a ring around it.  This is a stage
that you can get into if you are using short strokes with pressure on the
edges of the tool.  The cure for this is to insure that it looks like there
is enough material at the edge that you don't get a TDE and do a 1/3 length
stroke with little weight on the glass.  One hand in front of the other and
both hands weighted evenly as you do the stroking. Bob May
