The 10. Pz.Div. was one of the spearheads in Operation Taifun, the German attempt to capture Moscow in October 1941. Its tank component was the Pz.Rgt. 7, whose war diary has survived, in file (BA-MA RH 39/99). All data presented below is taken from that source.
On 1 October, the panzer regiment had 41 Pz II, 82 Pz III, 19 Pz IV and 10 Bef.Wg. operational. Ten days later this had shrunk to 29 Pz II, 66 Pz III, 21 Pz IV and 8 Bef.Wg All in all, a reduction from 152 to 124, despite the slight increase in the number of Pz IV operational.
On 21 October it had been reduced to 22 Pz II, 35 Pz III, 12 Pz IV and 6 command tanks. It seems that the workshops did manage to put tanks back in running order, as the number of operational tanks rose to 22 Pz II, 43 Pz III, 14 Pz IV and 10 command tanks on 1 November.
It would have been good to compare this to the daily tank losses (irrevocable losses), as they are given in a table in the annexes. Unfortunately, the copy I have received does not extend to the left margin. Thus, I can only see the month, not the date, which is given in the leftmost column of the table. However, it can be concluded that the losses in October amounted to 8 Pz II, 15 Pz III, 1 Pz IV and 1 Command tank. It should be noted that the table gives all tank losses from the beginning of Operation Barbarossa to April 1942, even showing in which company each individual tank loss occurred.
We could see that between 1 October and 21 October, the number of operational tanks shrunk from 152 to 75, a reduction of 77. During the entire month of October 25 tanks were lost irrevocably. Most likely, some of those were lost after 21 October and also some vehicles were most likely repaired between 1 and 21 October. We saw that the number of operational tanks rose by 14 between 21 October and 1 November. Given a similar effort from the repair services, around 25 tanks could have been repaired between 1 and 21 October.
With this in mind, it would seem that for each German tank destroyed, around 4 were rendered temporarily inoperable. This is a ratio consistent with other operations, as long as the Germans were able to tow away their damaged tanks (which includes tanks suffering from mechanical problems).
