'Good shape'! I expect the average continuous output for a city
dweller
might be significantly less, probably more like 100W. That puts you up
to 1500 people with 3000 feet. Hmm if each eats 1 kg grains a day then
just feeding them for a year will cost you 600T! Do you think they
would
expect clothes and heating as well?

Doesn't seem very efficient to me, but a heck of a good-sized hoeing
gang.

remember to add in the administration and motivation costs as well.
overseers with whips don't come cheap :-))
