When you click on a ship durring battle and then click the individual weapons, Multiple Warhead Missiles do not keep stats correctly. Multiple hits per shots are recorded, so the hit percentage goes way over 100%.
Other missiles with multiple warheads do not have this problem.
other missiles just have a single warhead,the countermeasures dont count as a positive hit
on the other hand,MWMs have no countermeasures,just warheads… every one of those is counted as a positive hit as long as it lands, however the shot amount is calculated normally
its easy enough to do the math yourself (or observe and make a educated guess,thats what i do,im lazy), i believe finding a fix to this bug/feature would be overly complicated,as it would need a overhaul of the statistics system
