This is a 3-frame improvement to UserFiles/Info/638874688943283518, reducing the total time from 499 frames to 496 frames.
The difference is entering the house with
w instead of in. On its own, that only saves 1 frame, but it also happens to tweak the RNG enough that 2 frames of delay for RNG manipulation can additionally be removed.
I learned that
w would work from bug #25 at http://www.graeme.50webs.com/infobugs/zork1.htm.
