I've made 10 tests with sloth, 10 with prod 1 and 10 with prod 3 taking all provinces around the capitol on Parganos (map without special start locations)

With sloth 3 I had more than 300 ressources 1 time / 10, less than 150 2 times /10
With prod 1 I had more than 300 ressources 5 times / 10, 6/10 once prod 1 was on all provinces around the capitol , never less than 150
With prod 3 I had more than 300 ressources 6 times / 10, 8/10 once prod 3 was on all provinces (only 220 in one case but I had just 2 neighbours, 296 in the other)

Perhaps it's a little too random to use huge ressource costs on a map with fully random start (ressources are very dependant of a correct first province), but with balanced start locations (say 4+ neighbours including one forest or mountain) it works well.
