It's not strictly modal, "when doing X use height Y" – I just find my posture preference changing slightly over time. I suppose long writing/coding is a bit more active/upright (higher), while long reading/browsing tends to involve a forward or alternating side-lean (lower). Shoes, time of day, and other recent exertion seem to be factors as well. And I alternate to seated, for hours or sometimes days at a time, for variety. I suspect I'm more likely to start a new project or do many small independent tasks while standing, and more likely to work-through a lengthier, involved task while seated... but I haven't kept careful notes.
