This is wrong build. I did 5:34 on fast speed in singleplayer and I didn't have best boars + clicked with 512 food, etc, so I imagine ideal time on slow speed + sp + 1 perfect boar is around 5:15 - 5:20.
I have no idea how you got to 5:22 with 6 vills (7pop), because I tried like 10 times on basically ideal Arabia and my best was 5:24 with 6 vills. Every important situation was slow speed/pause, singleplayer. Clicking at 501-503.I just got 5:22 trying it. I assume with perfect boar close next to scout, you can get towards 5:13/5:18
