The hood is about 24 inches by 24 inches if I recall correctly. Something very near to that, anyway. As far as I can tell there are no dim areas anywhere in the entire tent so I'm guessing you are seeing something in the photos that I'm not seeing. As far as when I stop tucking, I can't tell you how many days in it was... I don't think of things that way so I wasn't counting or anything like that. I just tuck tuck tuck until the stretch stops, or at least slows way down. You can easily get a feel for this by just doing it. Once the stretch downshifts, and you aren't tucking twice a day anymore, or even once a day, then you know you will just need to level out the canopy as soon as possible because you are running out of time to do so.
Hard to put into words, but easy to understand in practice.
