Overall, I have very serious doubts about the fairness of completing the map in less than 3 weeks.

Doubt is an integral part of human judgment. But before expressing it, one should consider whether they are sufficiently competent in the matter. Perhaps it would be worth listening to what others have to say? So, in addition to Romanuel's post, I would add that, if I didn't miss anything, the map has an obvious and easily achievable limit in terms of days, and it's even too easy to achieve. The limit is 7 days, and that's probably how many days the winner and prize-winners will have (or even less, if I missed something). I won't judge the maximum amount of experience, as I haven't been involved in optimizing secondary criteria in tournaments for a very long time, because, as a rule, this is a rather boring process, at least for me.
