I think you need to work on your specification more. You said something about averaging the last two weeks of downloads and putting the prefetch time 30 minutes before 80% of them. Why? You haven't specified. Why not just do it before all of those times? For that matter, why not prefetch at midnight the night before? There's presumably some constraint, like you need the latest content possible. If so, then you need to specify the maximum tolerable oldness of the content. Or the maximum average oldness. Then you need to specify whether you care if the user sometimes fetches un-prefetched content, or what percent of the time that's allowed to happen. The way you've presented it here, it seems to me that simply caching the first download would be sufficient, or as others suggested using a normal caching proxy like squid.

I think after you've really specified the problem, the solution will probably fall out naturally. It seems to me, however, that you're less concerned about solving a problem than trying to find a problem. If so, then maybe studying up on math and AI really is what you want to do.
