What? The second sudoku with gsfr ~99500 had 14 points with your rating? It was the highest rated with your rating and the lowest rated with gsf.
I see there is little correlation between your approach and gsf.

congratulations for the new Explainer record, Mike.
My rating is not so exciting, 16 points, but for the first hard step it needs 6 subnets (!), which i think is a record, too.

Well, it seems not to be true for your nightmarish puzzleravel wrote:Sudoku Explainer is the only program i know so far, that can solve the hardest puzzles in human readable (and graphical) form. It is also great for "normal" puzzles to look what techniques it uses to solve them….
[Edit:] With version 1.2 now also the current hardest puzzles can be solved.

A rating above 99990 says, that it cannot be solved with contradiction chains using basics and multicoloring. In the list above there are only 8 other puzzles with this property ([Added:] Mauricio has posted 2 other ones here, which have been lower rated by my program).
