I dropped my boil to 30 minutes on that run and was fully put away and cleaned everything just before the 3 hour mark. And with more hop bursting, you could get that boil down WAY far...like 15 minutes probably for low IBU beers.
Could under 2 hours be possible for a full all grain? Oh baby!
I'd be careful dropping boil times, you want to make sure you kill the bad guys and what about hot break, there's some important chemistry happening in them thar boil.
20 minute mashes make more sense, if you hit your percentages then it's long enough. I prefer to take my time but I have a HERMS setup.
