Hi,
when a pancor faces 2 targets and both have 2k life while the pancor has 6k attack damage then only 1 target will be destroyed. The remaining damage from the shot is lost.
Pancors have 36 shots per volley so they SHOULD be spreading the life exceeding damage.
Example Battle:

There you see he only destroys the 1.4k life mudkips that are remaining. But leave alone the remaining scavengers and NOT dealing the damage that have exceeded the mudkips life. The scavengers then got killed by my providers roughly 1 seconds later at 3:41.
Edit: Another Example.
