Yeah I thought that might be it, but the thing that threw me when trying to figure it out was this:
If I add that forward grip, volume/weight goes up, and aim speed goes down.
Then I take that off, and try the gyroscopic stabilizer I was looking at in the first place. Volume/weight go up, aim speed goes down. All seems orderly, right?
So then I try putting the (useless) forward grip on with the gyro. Volume/weight goes up as expected, but aim speed stays the same as just having the gyro alone, like it was just taking the worse aim speed of the two mods rather than adding them together.
But if it really is weight, then I guess there’s a threshold it has to go over before it suddenly ratchets down to the next aim speed? That’s rather counterintuitive.
Anyway, long story short, there’s no way to get the repeating crossbow’s dispersion down to anything lower than 166+120 before adding ammo.
Summary
Huh, I shouldn’t have made the font so huge.
That’s -75 dispersion between the three mods, but only -25 in the results. Is anybody else seeing this weirdness? I also notice that the dispersion doesn’t seem to add up right between the weapon and the ammo, but the mods still only make a -25 difference between when they’re off or on. I’ll have to try some other weapons and see what’s going on.
