UVZ is very consistent with the 60kp/h figure for the prototype BMPT’s (including BMPT-72, though for that I am not 100% certain whether they have conflicting figures in other brochures that I havent seen yet)
Aswell as the 48t (BMPT Prototype), 44t (BMPT-72 Prototype) and 47t service-bmpt figures.
In any case, I would value UVZ’s figures as more relibale than such from rosobonexport.
Your 47t figure for the ingame version is essentially pure fantasy as it contradicts several OEM brochures, infosheets from exhibitions, website statements etc.
And then we can also consider that the ingame BMPT has additional addon-side era (tiles) available, which do not magically make the vehicle a ton lighter by adding stuff to it.
You’re essentially going through several brochures, sometimes for what are literally different configurations/vehicles alltogether, pick and choose which values you like and ignore the others that contradict them or others and then start throwing them together to build a vehicle with characteristics you wish it had, rather than such you can prove the ingame-vehicle did infact have.
I had a feeling this was what was happening, based on him ignoring the fact that the BMPT can survive ammo racks and only wanting to speak about problems that would buff it.
I wasn’t able to make any confident statements, though, as I don’t have these manuals you do.
BMPT is the worst joke tank ever !!! I dont know how many deadly and fatale shots I fired and it still lives. Besides … the rocket pod does not explode when hit ! AND the ammo rack also does not explode when hit !!!
