Definitely, the mentioned 11 Hartmann claims were already "confirmed" by Propagandakomapnie and the GröFaZ himself. And looking at H.'s claimlist one can definitely say that he was not as heroic as many "Sturmovik- and Bomberkillers".

But who can judge on that? His advantage was: He survived.

Anyway, I would not say that the Bundeluftwaffe looked into Hartmann "frauding" or not, that was a different time then now, the whole democratic Germany was full of Ex-3rd-Reich people in high positions. They needed good people as well as "Aushängeschilder".

Overcaliming itself is definitely something personal (frauding also), as it also happens in todays world:
Some humans are selling themselves as "expensive" as they can, others do not want/need this. One more (very small) group even makes up some stories about their successes, but they are definitely a minority and I guess they were also back then.

==>
1) I think overclaiming is stronger in some pilots/persons then in others
2) I would not call them liars, but over-optimistic (also keep in mind their age: 90% = 20-25...)
3) I don't know what is the sense in identifying THE overclaimers in VVS, Lw, USAAF, ...
EDIT: Can anyone answer point 3 please?
