The tables illustrate, at least, how much the SU had lost by 42:Paul Lakowski wrote: ↑27 Jun 2019, 19:44Harrison does a good job showing how the SU economy reach cross road by mid 1942. Only thing that saved them was the value added component of Lend lease.

-Population decline from 167mil to 105mil based on pre-war distribution
-GDP decline of ~40%
Note that Harrison uses "average values" for 1942 - I'm not sure what to make of that statement. If we assume the 41-42 would be roughly doubled if Germany had occupied Stalingrad, Kuban, Rostov, etc. for all of '42 then we're approaching a 50% GDP decline and a population base below 100mil.
Now consider adding everything behind the A-A line to the loss column. Pre-war Siberia (Urals and eastwards) was ~40mil population. Central Asian countries were ~20mil but of dubious loyalty. So it'd be a stretch, IMO, to say that an SU beginning from the AA line in 1943 would have been able to mount half as much resistance in 43 as OTL.
