An issue for me is that factories are usually at 50% immditely after move so start producing at that rate 7 days after someone decided they should start being dismantled. I don't know if this is realsic, but will start a thread to find someone who knows more.
On average, it took roughly a week to two weeks to put a factory on a train, move it to its new location and take it off again. Another four to six weeks before most were up to full production again (some notable exceptions to that - some heavy industry took six months and more to get back up to full production). But... many Soviet factories had in fact begun 'evacuation' in 1940 and early 1941 with 'shadow' factories already being set-up prior to the German invasion. Maybe not something upon which you can base any kind of discussion unless you've discovered that the modelling of the Soviet economy is wrong because we're dealing pretty much with abstractions of abstractions so should be looking at output really and whether that's reasonable.
