Don,

I ran the suite at 60 seconds to get myself a better starting point. I
now have 647 right. 9 of those solved at 20 sec are now back to
unsolved. These flakes are 390, 470, 475, 489, 597, 666, 702, 824, 826.

I have 34 unsolved in the first 200. I'll list them as a review of work
in progress.

Legend: UNS - Key is correct, not solved
        SID - Key is correct, found side solution
        COR - Key is wrong or insufficient, found right solution
        BAD - Key is wrong, and there's no solution
         ?  - Awaiting forum's verdict

No.    Key      My move   my score   category
