The first table, prepared by Charlie ( http://www.anno-zone.de/Charlie/index.html ), shows the productivity of industries. 'Combine' values are for 2 farms and 1 processing building, except for the Grain Combine, which is 4 farms, 2 Windmills, and a Bakery. The table is included here for the benefit of non-German speakers (like me). Min (minute) values are for one cycle - one cycle is about one minute on most machines.

Lord Khang cites the following yields from food production:

Lord Khang conducted a further test: "Test was run for 10 minutes at Quadruple speed after the packages had a chance to gear up. In each package a single marketplace was dedicated for final product haulage. In all cases this marketplace was placed directly next to the end producer for zero travel time:

Lord Khang also compares different methods of alcohol production directly:
