You'll have to believe me that this is unusual. It implies a great deal of strain energy at one spot. It's an ideal precursor for an M9+ here, but the odds are still 1 in 100. Maybe only an M8. :) but we usually have M6's for an M8, and M7's do the M9.
So, in the next few days, if this all dies down, then I'm a fool for even mentioning it. Nobody else would. :)
