Brassing up a fixed position (house, fortification, tree line) with MG fire to allow a rifle section to move; a sustained, 450rpm steady is going suppress the defenders as effectively as 900rpm (or even 1200rpm) bursts.
No, its not.
Im not sure in what language, or reality is firing 400 projectiles at something as effective as firing 1200. Or rather, firing 400 at 1/3 of a time.
Likewise, your assumption of a 4-second bursts for the Vickers is particularly silly when assuming you're stopping a company or even platoon attack.
Yes, its so silly that it is about the value defined as "burst" in Vickers manual. Which also recommends firing at 4-5 second bursts at long range.
So, let's say 4 second burst, 30 rounds for the Vickers (as opposed to 40 for the M1919, 60 for the MG34 and 95 for the MG42). Of course, the lower RoF does mean lower dispersion for the gun (as does the lower barrel temperature), something I note you carefully sidestep discussing.
Saturation and hit probability on the target is also the same, of course, because 400=1200.
Apparently, this won't produce suppression. Do you have any evidence to substantiate that?
Yes, but Im waiting for the evidence that 400=1200.
...there are only 3 infantry companies in a German division?
Since we are pivoting from "muh long range fire" to fixed positions and tree lines, and 400=1200, apparently yes.
