Daddy Of All Gattai, all Windoku's this time.
Ruud's challenge about the biggest kind of Gattai in 2007: 85 overlapping Sukoku's, that inspired me some years ago to solve these kind of puzzles, by hand.
I never could solve however his 85-Gattai with vanilla Sudoku's https://sites.google.com/site/sisesuso/gattai.
This is a similar 85-Gattai: All Windoku's and it should be easy because there is a way of working to use Singles Only (no special methods needed).
So the SE rating is 1.5 at most. But that is a very very very subjective rating.
4747 cells to solve and it is symmetrical up/down and left/right. That should things make a bit easier. But it is not.
Do not start in the NorthWest but rather in the South.
Have a nice Xmax holiday 2019....
And for Solver friends:

Do you have a list of all the grids, or a paste friendly alternative?

You have on your page the header of your BOAG, but the puzzles are from "Daddy of All Gattai #2 (November 15, 2007)" (which don't allow windoku)
This one only solved without windoku constraint within 5 seconds.
Added the #85/XWAPG/ format for easier pasting, could add the others too, but there were no examples. There was no specification but I guess that is what it means.

The first link in this stream is to my 85-Gattai Windoku's picture.
The second link is to the original 85-Gattai vanilla Sudoku's of Ruud, who inspired me greatly.
The third link is to my homepage link with code-lines.
No XWAPG or whatever is appropriate/applicable, to my knowledge

The third link: https://sites.google.com/site/sisesuso/examples/85-gattai-doag
Puzzle #1 The JPG image is bigger than it appears
In code: ...[Your puzzle header][puzzles from Daddy of All Gattai #2 (November 15, 2007)]
So code conflicts with picture 1 and picture 2 with pencilmarks.
With Pencil Marks, again the JPG is bigger that it appears:
Extra formats would work because #85/W/ is windoku for all puzzles, and for your other puzzles you have used those other letters.

Hmmm.... My new Visual Studio .exe in 7.8 seconds...
lesser than 2 minutes.
Your solver is definitely more flexible an faster than mine.
Chapeau.
It took me 4.5 hours to generate the puzzle #1 with Windoku's.
Busy with DOAG #2, all Xsudoku's

Thanks 1to9, for the 2.5 rating . That is because some grids have a 2.5 rating, which is a direct hidden triplet, is it?
But the whole puzzle can be solved with hidden/naked singles per row/col/box. That is 1.5. How do you calculate?

I pass each grid to SE to solve 'as far as possible' using the basic techniques. Some basic techniques can be disabled, leaving only hidden singles (1.2,1.5) and naked singles (2.3), the DOAG still solves with 2.3 rating.
