I don’t think I’ve ever seen a community which did more poorly (than it might do otherwise) because it’s members understood each other’s points too well.
So I don’t recommend worrying about writing too clearly, but rather to either balance your time against the group’s (per considerations like my above points) or to run yourself against some sort of constraint(s), like time pressure or the upper bound of how much you can care.
There’s a (very reasonable at this time, I think) emphasis in this high-preformance day and evening lighting on trying to match natual brightness and spectrum.
Have you come accross any good data or models for late-day/early dusk?
I ask because while there’s a lot of good data and models for mid-day solar illumination, I don’t know enough to know how much to trust them towards the end of the day (which I suspect is not really the designed use case), nevermind stuff after sunset—and there’s over an hour between sunset and astronomical dusk.
(But yes, for midday… lots of models to choose from. The SMARTS model seems like a good choice. Good-enough accuracy, covers spectrum from 280–4000nm, easy setup, and has relatively few inputs and outputs to worry about. Big comprimise is that the diffuse illumination is treated as uniform, and it doesn’t do clouds.)
