AGM Point?

Whenever I am flying a helicopter with guided munitions, there’s an indicator in my HUD saying “AGM Point” with a number next to it. It’s on the left side together with all the other flight information. I’ve never been able to figure out what’s up with it, and I could find any info on it. So what does the number mean? (It’s not the amount of missiles I still have, obviously).

If im not mistaken that’s the distance to your target, and if you see a lil count down next to the AGM that the timer until impact.
