Overclaiming was not limited to air-to-air combat. The same kind of remarks were formulated about Typhoon claims on tanks in Normandy. So I'd say it's not surprising...

A tank is a small, mobile, camouflaged and armored target. Besides, a damaged tank can very often be repaired because, unlike a plane or a ship, it doesn't crash or sink, so, if one is not forced to pull back immediately, it is perfectly possible to work on it. And, as Franek just said, overestimating results is common... All this taken together leaves plenty of room for erroneous claims.
