I noticed that there is an inconsistency in the number of edited posts between the "editor stats" (which is the dialog that you can see in post revisions) and the user profile. For example, according to the editor stats, I have had 102 edit suggestions approved:
while on my user profile, the number of edited posts is 61:
which is also in accordance with the progress on the "Strunk & White" badge (edit 80 posts).
So which of these numbers is correct? I had two ideas to explain the difference, the first being that the editor stats are network-wide (for all stack exchange sites) while the number on the user profile is only for Physics SE. However, a quick check showed that the editor stats show different numbers on different sites (the same is true for the user profile).
The other idea was that the editor stats include the number of my own posts that I edited. This could technically be true since the difference does not exceed the number of my posts, but edits on your own posts do not have to be approved (which is suggested by the editor stats) - if anything, edits on own posts could be included on the user profile which does not specify that the edits were "approved". However, this obviously would make no sense since the number is smaller.
So why is there a difference and which is the "true" (i.e. edited posts of other users) number?
