Low Element number causes odd FPE & HPE increases - at times

[Wiedrock]

There is an oddity in the game (since forever) that elements that have a low quantity perform better or oddly well at times.
Sometimes it is just HPE (Urban example - Urban is special as we know), sometimes both FPE and HPE.

Some examples.

Another Armored Car going crazy.

Does sound odd. Is this repeatable from a save? If not, then unless asking AI to figure out what might cause this comes back with an answer, it's going to remain a mystery. There is a way that an element can get multiple shots off if lucky, and there's also a way that an element shot at will shoot back if missed. I don't think the former allows for multiple chances to fire, but maybe. Then again, do these weapons have some big ROF that might cause some anomaly?

I don't know if its repeatable, but this happens... A LOT
