The numbers look kinda right to me although to be completely transparent, I am working from memory here and I haven't read the small number of books I had for quite a few years (they've been packed away for about half a decade now!)

As I understand it, Soviet vehicles were a little more fuel hungry than comparable Western vehicles but their delivery systems were also not particularly efficient. The general notion being that they planned for a hard & fast push as deep into the frontline as possible and if the unit got bogged down, the next unit would take over the push and the stalled unit would take that opportunity to repair & recover. They would continually leapfrog combat ready units over bogged down units until they achieved breakthrough.

In regards to food, the Soviets always supplied less food per individual compared to the West, the Soviets expected some localized foraging to supplement their needs but they also supplied just the basics and none of the variety that the West supplied.

In regards to spares, again, with the mentality of leapfrogging a combat ready unit over a booged down unit, technical services from the rear could be brought up to repair & recover the immobile unit because (theoretically) the stuck unit would now be back from the frontline due to the combat ready unit having pushed forward.

As for ammunition, despite what the Soviets wanted the rest of the world to believe, they knew that their tank gunnery was not as effective as Western systems and they knew they would have less hits on target and thus needed to supply more ready ammo to compensate. Their general problem was they typically had smaller vehicles and didn't have the capacity for as large ammo reserves as comparable Western vehicles but the mentality of pushing through bogged down units (and the idea of those units being somewhat disposable) with fresh units to continually push back Western forces also meant to a degree, that a unit would not need large ammo reserves - it wouldn't be around to fight for as long as a Western unit!
