You can take down an 8 million block shield (32.269 million capacity) in about 6.14 seconds with 360,000 AMCs set up as 2000 180-unit guns, or in 1.02 seconds with 2.16 million AMCs in the same 180-unit guns (12,000 guns).
If for some reason you actually used the same amount of mass on AMCs as shields, at 8 million shield units versus 44444 groups of 180-unit AMC guns (actual mass of 7,999,920), you would take down the shields in only 0.2764 seconds.
Of course, I don\'t think that StarMade is capable of handling anyone firing 44444 guns simultaneously right now, so efficiency may be reduced by the need to use bigger, less efficient, guns... It might be able to handle 12,000 simultaneous guns firing. Possibly.
