I see a lot of Ng+ glitchless runners utilizing the rocket pistol quite a bit during their runs. Since I don't actually have it, would it make a significant difference in time for me to have it?

Also would getting the movement speed bonus from the dukes kitchen make much of a difference?

With my current best being 1:46:00, would I see much improvement from those two things?

I know that there is a way to slip past baby after getting the fuse so you don't have to run back to the bedroom and hide, but I'm having some trouble pulling it off consistently. About 70% of the time baby either insta lunges and I die, or baby decides it would rather not lunge and just follows me in the kitchen and I... Die. Seems like it would be a pretty large timesaver so what could I do to pull it off with some consistency?
