How can that be, if the server status page list plenty of tasks ready to send?

Because the feeder gets 200 (I think) tasks every second (I think). It depends on when you hit the feeder.

I wonder if they internally track something along the lines of "average number of tasks in feeder queue/hr".

There are two bits to the feeder - the big (hundreds of thousands) and the smaller (loaded with one hundred) allocation pool.
The big one is supposed to be maintained at about 300,000 "automatically", the small one is a simple table which (as far as I'm aware) will only take 100 entries.

Nobody sits there watching that these queues are behaving themselves - most of the time it would be a very boring activity. I dare say they have automated monitoring which triggers alarms if the big queue goes out of bounds (as it did after Tuesday's planned outage by hitting about 1,450,000)
