I guess you tacked Fine 70 on the end before you ran the test, huh? You have 1
more answer than me :)
GLC gets Fine 70 in 0.03 seconds on my machine, so it would chalk up 22/36.
I had a look through the results, and it looks like there may be some more
solutions to some of the positions...

If anyone else can confirm or deny these, please do so.
Cheers, Tim.
PS. Some of the others look suspect as well, but the idea may be to draw so
it's not so easy to tell.
