What are the fastest advance times possible?

I just played around a bit to see how fast I could reach the feudal and castle age.

I managed to reach the feudal age at 6:40 with Mongols on Yucatan so I could make use of the faster hunting. I only built one house and made only 6 villagers (so 9 vils total) because I feel like if I made any more villagers they wouldn't pay for themselves before I clicked up and I'd also need to chop more wood to pay for the house. The only way I got food was hunting.

My fastest castle time is 11:57 with malay once again on Yucatan. I started fairly normal with 7 on sheep and 4 on wood. Then I put all villagers on food (mostly hunting) until I had 23 villagers. I then clicked up to feudal and once I had enough wood for the buildings I moved the 4 villagers on wood to food. When I reached the feudal age I used about 6 villagers to build a market and sold my stone to get enough gold. I also built a blacksmith simultaneously and once both buildings were complete I had just enough food to click up.

Obviously it's a terrible idea to click up this fast as you're entirely stuck once you reach the next age and can't do anything with it, but I don't care about that, I just want to reach the age as fast as possible.

This made me wonder what the fastest possible advance times would be. I am decent at the game but by no means a top player so it must be possible to do it faster than I did it. What are the fastest feudal, castle, and imperial times you know of?
