I don't know if you're having trouble with all the feeds you're working
with, or with a small subset! But here is my own personal experience with
PSHB in case it helps:

I subscribe to a lot of feeds and I've learned that, in general,
PubSubHubbub is not a reliable system. It's a distributed system that
involves the publisher, hub, and subscriber communicating over the Internet,
which means that any bug or issue at any point in the chain will cause a
notification to be lost. Often the issue is when a publisher doesn't send a
notification to the hub, and sometimes the hub is to blame, and so on.

The way I handle it is that I have a slow polling process that fetches feeds
once a day. If my polling process fetches a post that's not in my database,
then I know something is wrong because that post should have been received
already through a PSHB notification. So I mark that hub is "potentially
broken", and put that feed on a faster polling process for a month (in the
hope that the hub gets fixed in that time), and then repeat the process.
