I use a Firefox extension to pull the next 10 pages, inline. I then convert all the links to open in new tabs. I'll slowly work my way through the resulting Frankenpage.
When I first started doing this, I only pulled 5 pages, sometimes waiting a bit to then pull 5 more/deeper. I was worried about excessive use -- including triggering whatever blocking you have in place. Eventually, I tried 10 at once. I've found that 10 is about as deep as I want to go into the recent history and keeps me fairly current with daily browsing.
I hope this use isn't considered excessive. It's run just once or twice in a day, and the results are simply for personal consumption.
As I (somewhat vaguely) recall, I began doing this when and because a change made the "More" links expire more -- as in, rather -- quickly. That was a time when you were working to keep HN from bogging down and choking on its memory usage. I wanted to see a few pages into the history without a bunch of overlap and having to start over from the first page; and pulling the subsequent pages all at once worked well for me as a solution.
I'll have a look at the revised RSS feed.
