Using your puzzles as seeds, I've obtained some slightly higher ratings (windows open):
Code: Select all
.1...23.4........5..................6.3..7...........64........8.........7...5...  13  ED=10.7/10.7/2.9

This puzzle has some loose clues (change one, another becomes redundant), giving (so far) these 11-clue puzzles:
Code: Select all
................1..2.........3..4.............5....6.......2.....71..38..........  11 ED=9.1/2.9/2.9
................1..2.........34.5.............6....7.............71..38..........  11 clues, ED=9.5/2.9/2.9 
................1..2.........34.5.............6....7.......6.....82..3...........  11 ED=10.2/10.2/2.9

Is this a preview from a newer version we can expect?
Code: Select all
.1..287..7.................4...6......6......9........1...................7..53.. 13 WX ED=11.3/11.3/2.8

With the latest public version I got this:
Code: Select all
.1..287..7.................4...6......6......9........1...................7..53.. ED=11.4/11.4/2.8

No. This is from custom code, essentially test code to check what changes are needed for this windows closed/open functionality to work! I'll have to figure out how to make this work in the SE GUI, this will take a few weeks.

I have made some changes to the Chaining code (e.g. support for variants regions), so it may well account for the rating difference (not too sure about this!) - SE (2022.1.4) gives ED=11.4, when my current version (unreleased) gives ED=11.3.

I checked your 12 clues example with the latest available version, and it's quiet impressive the use of windoku and diagonal blocks in generalized intersections and chaining methods.
But it's rating is slightly lower:
Code: Select all
17.3...8..........2...................5...3..8...6............9..........2.....1. 12 WX ED=11.6/11.6/2.6
