Conversion and efficiency isn't something I know much about. I guess my skill level hasn't reached that point yet, but this conversation has an eyebrow raised and I'll probably be looking into it more. Thanks!
Oversparging usually refers to excess water. The temperature and times issues coudl potentially be significant, but it will be hard to know without calculating your efficiency. There are plenty of good threads around to help you know how to do that. Realistically, though, so long as you held temperature properly for the first 30 or so minutes, what happened after that is much less important.
Edit: Hot Side Aeration is a boogey man in homebrewing. It's not clear that it even exists, but it is basically a concern about oxygenating the wort while above a particular temperature. It's a non-issue.
