Played the BeebEm BBC Micro Emulator, and using FancyTimes 100% guide:

The one "timesave" I did was shortening all cardinal directions to their abbreviated N,E,W,S or SW, SE, NW, NE. I'm sure you can skip at least some of the points in the guide if not going for 100%, but tbh it's not too worth looking.
