If this is caused by several types of same-size missiles used, some not doing energy impacts, those NPRs are weiird.
Another volley group shot down, this time it was 16 energy impacts for 21 missiles.

For a change, while event log shows only amount of volleys in one group detected by thermal sensors, event log _file_ doesn't show how many same events happened in the one moment. So only amount of missiles in one volley for active sensor new contacts but not how many groups were there, just that there was a thermal contact but not how many of those, just that some missiles were destroyed but if turret hits multiple times this is shown here only once.
OK, I will add a printscreen of event log too, then. Note the line selected at the bottom of the 1st image and the top of the 2nd one is the same.
Btw, each of these destroyers firing have 2x twin-laser turret under one beam fire control and 3x twin-laser turret under another one.
Can someone explain where are those missing energy impacts?
EDIT: Read your reply only now, OK, this should not be caused by weird several types of same-size missiles then.
EDIT2: I have already battled another TG of this NPR so I have already seen such designs in use for this NPR, yes. As far as I know these missiles in question are their basic ASMs. But thanks for generalised summary.
EDIT3: One last idea: so far all volley groups arrived at the same intervals inbetween. The impacts/missiles ratio in this battle were: 18/21, 21/21, 18/21, 18/21, 12/15, 12/15, 11/15, 1/4, (one extra 5s interval - they apparently were reloading), 17/21, 18/21, 17/21, 16/21. The last one is shown higher and more keep coming.
