The FAQ states "The voting period lasts for two weeks after the conclusion of the event." but there are only 5 days left. Which one is incorrect? Considering that there are hundreds of submissions, 2 weeks would  probably be much fairer than the actual settings 

I don't see that text in FAQ, but in 

Judging Criteria:

"When the jam ends, participants will have 1 week to play and rate other submissions in the jam"

I also saw it

Q: Are there prizes?

Yes! Everyone that submits a game gets a free course on GameDev.tv. However, there are no prizes for winning or placing highly in the ratings, this is not a competitive event. Users will vote on each other's submissions across 7 categories (fun, theme aesthetics, music, sound, mechanics, and story) as well as provide comments and feedback. The voting period lasts for two weeks after the conclusion of the event.

They said on monday twitch stream that voting period is 1 week. So I think the FAQ has error.
