Is the floating reticle supposed to be very shaky when employing the ATGM with a human player?

Unlike Petrovich, the floating reticle(where you have to align it with pilot's reticle inner ring in order to achieve launch parameter) is extremely shaky when playing with a human gunner. In gunner's point of view, his reticle is dead-on the target, but It's jumping up and down probably for more than 5 degree on my HUD, even though I have the target right in the middle of the inner ring. It makes launching ATGM very difficult, and I can't tell If it's due to de-sync or operating errors.

 

Any advice? Thanks!

I just listen for the tone, Click and hold and it fires still. Not sure what the gunner sees but I just chalked it up to the mechanics and caculations of the ghetto CCIP
