Aces versus non-aces

[Leendert]

Not to start a lengthy discussion, but some fact finding.

The fighter aces and/or their claims hold a special interest for several of our distinguished forumnites. True that aces achieved a number of 'kills' to reach such status.
On the other hand, there were hundreds of other fighter pilots, 'non-aces' so to speak, who had air victories, be it even just one.

My questions are twofold:

1. Can it be calculated what the percentage was of aces versus non-aces in the number of pilots who are attributed air victories, including just one?
Here I mean air combat, not ground strafing or the like.

2. Of the total of air victories, how many by the aces percentage wise?

Since this is a subject not at all in my regular field of interest, I hope that other board members more familiar with lists of claims and/or aces can share their thoughts.

Thanks for help.
