Guys, you urgently need to do something to promptly update the table on the site. I think it doesn't really depend on the organizers of the parkour part of the competition, but, nevertheless, the best option is important. You have planned the competition in such a way that the weekend falls at the very beginning of the week allotted for the competition. Accordingly, it is very important for the participants to receive feedback on the submitted videos as early as possible so that there is time to correct mistakes. It's much easier for teams to get together on weekends, especially if the task promises to be really difficult and will require a lot of time and effort. I hope you will be able to cope with these difficulties. Sorry for my English (it's a translator)

If all the teams make challenge 6 in a couple of days, is there any chance that you will give challenge 7 earlier?

Yes, the task is really not a small random. But believe me, if everything is well thought out, you can reduce the randomness to a minimum.

Good luck!
