Just for example (as I know much more of such complicated cases!):
1. Losses of 4. Pz.Div. 1 - 20 September 1939 - one report:

77 Flak.Abt. = 0 + 0 (0) / 0 + 0 (0) / 2 + 7 (9) ------------- 2 + 8 (10); there is a typo somewhere?
3. Oberstleutnant Eberbach, commander of 35 Pz.Rgt. about losses of his unit:
35 Pz.Rgt. = 64 Tote, 58 Verwundete (maybe "Czech mistake" and there should be 85), 45 Panzer Totalausfall
If there were some small discrepancies, I wouldn't complain - but many numbers are completely different !!!
