Mark - some of us just don't care (me) and arguably, recognise it's essentially unimportant, like your best trading cards score or best conker at school. (Look up conkers if you have to - great game.)
The role of fighter squadrons is essentially defensive and to achieve air superiority so the war can be won by others. High scores by individuals, units or air forces are not a reflection of achievement in strategy, but a reflection of the strategic situation, and things like a target rich environment - or not. Higher fighter scores are often the result of being in a defensive situation, and defensive situations mean you are closer to losing, so while it's not a inevitable result, many high scores were achieved just before the battle was lost. (Exception - Battle of Britain). High scores on the offensive are either early in, or exceptional (Barbarossa - mostly ground kills, Marianas Turkey Shoot, a famous exception.)
The teenager-beloved 'which aircraft is best', and, more appropriately, hono(u)ring the bravery and individual guts of the airmen, and (rarely noted) the quality of their training and logistic support all come lower down the factor list of success than where, when and why.
So as has been touched on, wartime and honestly-compiled claims are almost always over-stated (although not as much as those that would degrade the
Luftwaffe experten hope) but what matter, as in war, and most other contests, who holds the field afterwards. If you dispatch the enemy's attempt at air control, however many
or few kills it takes,
that's what matters.
That'll teach you to ask a perfectly reasonable question carefully couched!
