I think that the accuracy of claims is not irrelevant when trying to judge the effectiveness of air units, specially fighter units. When looking the stats of certain units, the "top scorers" make a substantial contribution - thus it has some importance. Inflated kill/loss -stats give wrong picture of airwar and can lead to wrong conclusions. The more inflated the air victory stats is the more false picture it gives about the efficiency of certain air units, certain tactics and certain strategy.

The RAF failed to achieve enough positive results in 1941-1942 with Circus operations and the actual kill/loss -stats were highly unfavourable for RAF - big numerical superiority did not bring the hoped air dominance over Western Europe. Effectively just two Luftwaffe regiments (JG 26 and JG 2) tied down much bigger enemy forces and managed to inflict them bigger losses than suffered themselves.

How much did the inflated RAF kill/loss -stats with these operations effect in the continuing somewhat dubious strategy and committing too many Spitfires in rather futile operations is very interesting question. Many Spitfires would have found better service outside of Britain much earlier like sending them to defend Malta and stregthening DAF in North Africa by late 1941/early 1942.
