I don’t want to discourage anyone from participating if it feels right for them. Go for it and have fun! I might do it again sometime, but not for the foreseeable future.
My issue is that I have run into so many writers who feel as if they are failures if they don’t beat the clock or if they don’t play the game. I have been there myself. If you’re not the kind of person who produces great work on that kind of timetable, the problem isn’t you.
