11.7 is up to (at least) 35c - ........1..1.23.....2.45...........6.178...9.96.2..87.....8.7.9.89...21.7......6.

I haven't run a full check in a while, so maybe some other improvements when I do.

Ran a check on the 11.6+ puzzles; 11.6 is a new result (11.7 and 11.8 match my last two posts), I've also included puzzle counts and range of clue counts for minimals.

11.9 - 23c (5; 22-23c minimals)
11.8 - 32c (4; 29-30c minimals)
11.7 - 35c (303; 26-29c minimals)
11.6 - 37c (77; 27-30c minimals)

Some of the minimals for 11.7 and 11.6 were first found by hendrik_monard.

11.9 - 30c (see hardest thread; 26c-27c minimals, but only one rates at 11.9 with gsf minlex form, the others are 11.8 - haven’t checked yet if there is some uniqueness difference or if it’s just pruning differently)

Per hardest thread, 11.7 is now up to 38c... haven't found an 11.6 38c but probably only a matter of time.

11.6 is now up to 39c:

Code: Select all
.....1..2.12....3.4.5..3.61...17265....895.1..51634....435..12.1.6...3.552.31..46  ED=11.6/11.6/3.4
.....1..2.12....3.4.5..3.61...17265....895.1..51634....235..14.1.6...3.554.31..26  ED=11.6/11.6/3.4


Same puzzle apart from a swap among 24r79c28.
