OK, here's the best I can do at the moment.
First, see this link, which describes the start-up.
Then see 2nd link, which talks about the changes made a year ago.
See my feeble description of the processing cycle above.
After I passed along your query, I got this:
Hi Les,
We are getting a new graduate student to work on this EON project. It is gonna take some time for him to get used to it. Thanks for advice.

So, some days, you're the pigeon; some days, you're the statue. Progress is sometimes just about as slow as the processes being calculated. Could be wrong, but I read the response as being, "We're reasonably happy with what we've got and any changes are going to take a while."
They may not have the resources to do any better right now. As I explained above, it's not particularly a lack of processing power as much as the cycle of the processing algorithm. Not knowing any more about the overall scheme of things makes it hard to make meaningful suggestions. I, and others, have found some correctable items in the past, but unless you're there...
