Vikings - 24 pop FC in 15:21 on Arabia?!

Is this a known build?! Fastest FC I've ever played against and with 24 pop (23 villagers + scout).

I know pros can FC in under 16 minutes (and faster), but at my level (~1800 HD), this is unheard of. What a build. I'm not even mad.

Notes:

• didn't hit loom before clicking up to feudal

• took all deer (4) starting in dark age with a mill on deer and a mill on berries

• upon hitting feudal, researched loom and created no new vills

• built a stable and blacksmith to click up to castle age

• while going up to castle age, built a second stable

• upon hitting castle age, consistently produced knights from both stables (no blacksmith upgrades)

• no farms, no extra sheep or boar from laming, no eco upgrades, some TC idle time before clicking up to castle age after researching loom
