This seems oddly complicated, and, it's neither misleadin, or completely wrong. The numbers basically work, it's your capacity that's the problem. You can see the exact stats on the weapon themselves, and if if you have enough capacity to handle your alphastrike (and don't use shields at all...) then you can just balance your dissipation and come out even. If you have a flux-hungry weapon with a high reload, it's usually not something you want to be fireing 24/7 anyways. I like saving my AM shots for either cracking the last bit of a shield after a knife-fight, or softening up Armour for my flack weapons after I've cracked said shield. AM blasters are by no means a primary weapon, though you can build a flagship around them, you almost need some other form of weaponry. (I don't recall the scarab off the top of my head, so I dunno if that's possible for you) that flux per second is how much dissapation you'd need to be able to fire it whenever it has ammo and is off cool-down.
TL;DR
“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
use weapons as intended to get intended results, stuff isn't misleading, and the opposite of what you're asking for is already given, thus it's personal preference.
