Ok, we have screenshots

here and they show different prefire figures, however it doesn't explain the on-hit damage. Although consoles don't explain it either as I've just done the maths as follows:

Boost from 1 console: 170.3524

Console boost on retrofit: 26.2*3 = 78.6

Damage on retrofit (no consoles): 650.2

650.2*1.786 = 1161.2572

So expected damage prefire (with consoles) = 1161.2572

Actual damage prefire (with consoles) = 840.5

Difference: 320.7572

Console boost on Standard: 26.2*2 = 52.4

Damage on standard (no consoles): 650.2

650.2*1.524 = 990.9048

So expected damage prefire (with consoles) = 990.9048

Actual damage prefire (with consoles) = 788.6

Difference: 202.3048

So while the prefire damage increases for that 1 console I still find a hole in their maths. You can calculate it in percentages (as I have shown here) or in plain numbers (as I also have) and you should come out with the same results.

So either I'm wrong, after doing all my calculations 3 times in windows calculator, or the game maths is wrong, or there is a hidden variable
