Recently I tried to edit two questions, this one and this one. Both my edits were rejected by Community$\diamondsuit$, which I take as "automatically rejected", because they conflicted with a subsequent edit. Both edits were simply formal: I edited math formulas to make it cleaner and more understandable.
Now, I see that the second question has been put on hold so maybe this is the reason behind my edit not being accepted (but, is it?); for the first one I can not think of a reason not to accept my edit; subsequent edits by moderators fixed the spelling but, in my opinion, did not make the post more readable by including LaTeX rendering.
Since my edits were automatically rejected, what can be the reason of such a rejection? In particular, when there is conflict with a subsequent edit, which one is going to win? Is it reputation based, or decided by moderators, or what else?
Please note that this post is by no means polemic, I think that there is something I am missing about edit & review procedure so I would like to understand it in order to edit appropriately in the future.
