Maybe the UWP is not the right way to present data to the player. Maybe what's needed is a page talking about worlds in general terms (many worlds based on size, atmosphere, surface water, government, and so on), and only specifically mentioning starport codes and tech levels.
I agree. I've been playing (admittedly intermittently) since 1986, and I have to look up the UWP Every Single Time.
If someone set out to make the game as inaccessible as possible to new players, the end result might be the UWP.
