0.319 F/s gather rate of farms. Data sourced from http://aocstats.aocpip.eu/
175/0.319 = 548.59 seconds = 9.14 minutes
250/0.319 = 783.70 = 13.06
375/0.319 = 1175.55 = 19.60
This.i'm making 2 farms once my 2 boars are finished (if there aren't any extra boars), another 2 when i go up, and then it depends on my eco/civ/if i have deer, if i make another 1-4;
i do horsecollar once i'm up to Castle Age (before or simultaneously with the 1st lumber up) and add 1-4 farms to a total amount of 8. (in ara you would add more farms now, since you usually won't make 2+ tcs straight away, but yeah all depends on strat and civ)
i'm doing heavyplow once i'm up and in general i have enough farms by that time, so i just make it because i will have to reseed them soon. (i assume it's the same for ara, well i'm doing it like this, maybe other people do it diffrent)
