Am I missing something? iNoMed's stator reduction actually does shrink the bounding box, but neither of the subsequent stator reductions appear to do so.

[GUYTU6J]

Their reductions is population-wise, and hey, why aren't we taking population (or density) as a second criterion for size after bounding box?

And can someone look at my original question?

You’ve got a good point, in fact, reducing population might help with welding.

It could be useful for a self-destruct. Although, it's more than likely to be known.

EDIT:
It's known, nobody has ever thought of using it in a self-destruct though.

Is there a comprehensive list of sparked syringe glider extraction at different periods?

Not a comprehensive list, but there is a gallery in one of my user pages:

There should be two choices, one with optimized width and the other optimized height. The guntrue_125 reduction we are talking about works by replacing the latter with the former, and so I wonder if more reductions can be made that way.

How exactly are intermitting glider guns constructed for a desired period without making it a plain signal loop? Here are my first attempts: an excessively large period-2025 (45×45) gun based on one of the two-engine guns.

How exactly are intermitting glider guns constructed for a desired period without making it a plain signal loop?

Heh, I think you're probably already executing the traditional method:

1) For a given target period N*X, find a period-N mechanism that allows for an adjustable-length signal circuit, where the output of the circuit interferes with the input of the circuit in a way that creates pseudo-random feedback;
2) Adjust the length and see what period multipliers come out;
3) Hope that one of those multipliers happens to be X.

There's no doubt some clever mathematical analysis that could be applied to the problem, but then you have to build a CGoL model that matches whatever math you come up with... and that's likely to turn out to be big-and-awkward instead of the relatively compact-and-elegant lucky matches that you come up with with the "traditional method".

Oh, well. So the previous discoveries of IMGs are more of sheer luck.
Here is another smaller period-2385 glider gun; I find it weird that a tremi-Snark is required.
