[Laurent Rizzotti]

Just a thought: as the Luftwaffe confirmation system took months, and even sometimes more than one year, unit ceremonies or awards for 100th victory and such numbers were probably done when the 100th "victory claim file" was filled by the pilot and his hierarchy, not when the pilot received its 100th official confirmation.

So I guess that in this case, while on 19 May 1942 Dickfeld had done 101 claims, part of them were never officialy awarded.
