this pattern has potential to add 1500 puzzles to the hardest DB, mainly in the x/y/10.3 area.

My final count is 1881 puzzle to try to add to the potential hardest data base.

What means "try to add"? Pass trough serate?

[dobrichev]

So far I have 2047 puzzles having sufficient serate OR skfr rating. Of them 1860 have sufficient serate rating, many are still not rated by serate.

I am ready to share these partial results to save your time and CPU resources and to give you a chance to focus on those that aren't found/rated by me.

I didn't stop generation in the high area, 49 754 768 skfr rated puzzles so far.

"try to add" just because some are already in the data base and some have been posted;
As usual, I start with external sources when I get them, so still less chances to have aditions on my side.

I have now 12 ER 10.8
