What are you talking about? Gathering 3600 meat in 15 min? It takes exactly 1 hour to gather 3000 meat at goat mountain and not a minute less. It takes exactly 20 minutes for 900 durability on an advanced cooking utensil at 1 sec cooking (as it has a 0.1 sec delay from just regular ingame lag between crafts which I guess you never cared to actually test and just calculated 900/60 sec). 900 durability will net you ~3600 good feed in about 20 minutes as stated above once you have all the materials. 7200 surprisingly enough will take you double the time - 40 minutes. The math from my post above is 100% correct, test it and you will know. As I said before, stop throwing fake numbers in the air.
