Yes.
So if you have a CAD modeling system, you can get the, the, the inertias.
Okay.
The CM alpha, you need an arrow code.
And this was in here to illustrate the effect of changing the density of the medium, which you're flying.
Miller formula is garbage.
Don't use it.
I mean, if, yeah, if the zombie apocalypse is upon us, then you can use it.
Okay.
Okay.
I have actually started some work on a different formula.
to see if we can't do something better than Miller.
And it's one of those, you put it down and then walk away and forget about it.
And I haven't picked it up in a while, but yeah.
The Miller formula is much less than ideal and it's much less than accurate.
The reason for it is it doesn't take into account the inertias.
It doesn't take into account the air density.
And it doesn't take into account the effect that different bullet shape has on the pitching moment coefficient derivative.
So it's really a stopgap.
It's much less than that.
