The short term trims can do that and it's fine but your long terms absolutely shouldn't. If you look at the picture I put up you can see a little red marker above the white bar and a yellow one at or below it. That's how far my long term fuel trim fluctuates.
I only use my long term fuel trim to diagnose my problems.

That tells me there is definitely a leak somewhere. Maybe just a split boot but something none the less. I haven't heard about the screen on the iac but it might be worth messing with. You ever get a video up on YT?

Also how much have you driven it since reinstalling the cats? Cz if you haven't driven it very far your LTFT can be from before you reinstalled them...

You've already been informed to quit doing that....your creating problems. That's not the way to find leaks, it how you are creating them.
