Bravo !

[champagne]

I don't have yet the 10.8

[Patrice]

::: comment :::
There should be other 11.x, but difficult to find !

I got one ED=11.1/11.1/10.0 ... not playable : do you want it for your collection of hardest ?
and a 5th 10.8
but no 10.9 !

[champagne]

we have similar results,

on my side

1x11.4
2x11.1
1x10.9
6x10.8
and many 10.7 (3 diamonds)

::: comment :::
2 x 11.1
1 x 11.0
5 x 10.8
33 x 10.7 (including 3 diamonds)

but i've identified only 14225 sudoku for serate nested levels (>= 9.5)

Hi champagne,
I just found a ED=11.4/1.2/1.2 rank of generation : 26 681 571 / 26 968 944 it's a very late one
but it's an isomorph of yours

I think it's the end : my situation did not change above 10.8 except for this 11.4
1 x 11.4
2 x 11.1
1 x 11.0
5 x 10.8
43 x 10.7 (including 3 diamonds, 39 pearls, 1 other)

Impossible to find a 10.9 !!!

in the 26 968 944 generated sudoku (valid minimal - isomorph verified) I've rated less than 8%
2 011 936 full rated
1 994 663 by fr (my own rating software that can go up Dynamic Cell Chains)
17 273 by serate (these sudoku needed nested level rules)
The difficulty of your pattern is the ratio of sudoku that are in the range of nested levels ~about 10% !!!

if there is no improvement today, I will stop generation and rating this evening !
usually I never generate more than 30 millions sudoku for a pattern ...
