With salvaging lasers another problem plays as well, in that they are trying to target tiny tiny little bits of wreck which are moving, and they can just never hit it.
Seeing this behaviour a lot, where all my 16 salvaging lasers will be trying to hit the same little bit, and they all cross at the same point, well within range, just impossible to hit it. Sometimes I can target the tiny wreck piece and kill it, and all the lasers will seek out new targets, sometimes I can't even find it. Wiggling a bit so the lasers need to realign sometimes helps as well, but all in all it just stops salvaging dead.
Juicy generator RIGHT THERE, and all the lasers are trying to salvage a gnat.
