It is wath I said before.
I cannot stop searching after each found naked/hidden triple/quad.
I will look into this tomorrow, but probably you can do without a hidden quad.

OK, now i understand why your 100 puzzles have many 5.0, 5.4
- and no 3.2-4.0

[Hajime]

I run another batch job for 200 puzzles. All symmetric. For SER<5 and >3.0 this is the result:

thanks

and in the 200,
again probably many marked 5.0,5.4
where in fact the quad un-needed, right?

[Hajime]

No, in fact you can run a Batch-Out job in SiSeSuSo with a predefined layout (the WindokuSolo) and predefined methods (Pointing/Claiming, short XY-wing/chain, Fish, short X-chains,...), including some restriction (in the Settings Tab-page) . In this case "No hidden/naked quads".
These 9 puzzles where the highest ranked. All others of the 200 were naked/hidden singles.

[Leren]

If you are looking for quads try these.
