Maiden of crashes
It did not, I was firing at a 1000m thick plate of standard armor in order to maximize efficiency for both weapons by making sure there would be no overpenetration. And while its true that an alpha weapon is meant for 'massive upfront damage' rather than DPS it fails at even that because despite a 16 seconds reload the C/P is only doing as much block damage as 2.3 seconds of fire from a C/C array of the same size.C/P is a poor choice for DPS. It simply isn't meant for that.
Did the C/P weapon in your test over-penetrate at any point?
