A 12 cm cannon from SS does 6dx30 dDamage, multiplied by speed in mps. So 6dx300(2) p++ (non-decade) at 1 mps (or 5280 fps, ~ 1600 m/s)

The D-81TM TL Russian tank cannon is in High Tech. It's 125 mm, or 12.5 cm. And it's damage, with APFSDS, is 6dx30(2) p++. It's muzzle velocity, according to wiki, is 1700 to 1800 m/s, or better than one mps.

What is being used to justify the order of magnitude increase?

The difference in scale between 1 second and ten minutes. While most of that time is simply occupied with trying to get within range, it's still a lot more bombardment than a single second's shooting.
