My preference is to do a 90 min boil, I dont start counting down until im at a rolling boil AND the hot break has passed. After that happens, I boil for 30 min then start my hop schedule. BUT I did try a 45 min boil the other day just for the sake of experimenting. I will probably not stray from my 90 min boils in the future though, I like caramelizing the wort a bit.
