^Nobody in this topic has expressed anything remotely resembling anger. It's a matter of taking the game's physics and the level design into account, and considering "where can my route be improved upon, and how much time does it save". Unlike in the classic games, there aren't zips or boundary breaks to be found, so it's easy to envision a probably max.
That said, I do think 1:13 is just past the verge of impossible... I know there's a section of the level that I regularly screw up, but I know for a fact it doesn't cost me 13 seconds (my time is about 1:26 btw). I've considered using my saved Sonic Booms in almost every logical spot in the level, and I've compared the time spent using the barrel gimmicks to the time spent dodging them. I'll believe 1:23, maybe, but not 1:13.
