That's not Krivosheev's numbers. You just cribbed it off Wikipedia, who quotes Glantz and not Krivosheev. And if you know Glantz then you'd know he counted operational losses (permanent losses + tanks in the repair yard) and not total losses; otherwise the Soviet counter-offensive after Kursk could not have happened because officially the Germans had more tanks left than the Soviets. This did not happen because German loss figures are in fact understated since they only counted permanent losses, when in reality most Panzer Divisions had only two dozen working tanks left out of a hundred while the rest were in the repair yard. Of the 3,000 or so tanks the Germans started out with, only around 300 were still working that could contest the counter-offensive; yet as usual rather than declaring 2,700 operational losses the Germans only reported the 300 permanent losses.
Krivosheev had real difficulty in figuring out the Soviet loss rate, and in fact if I recall right he claimed the Soviets only had 5,000 tanks but lost 7,000, which is why nobody really relies on him exclusively for loss rates to begin with.
