I struggled mightily on what detail was meaningful for the newbie player.
While a referee needs to know exactly what each digit means, and some players will eventually want to know too, the new and/or beer-and-pretzels player doesn't, and can't, process it in one sitting, and may never have to know or care.
Let's nail down the use case.
* What is the player's background? Are they >20, 20-40, 40+? It matters for context, e.g. "Transistor Age" is probably meaningless to anyone < 40.
* What do you want them to have learned by reading this?
* When are they likely to refer to it in the future?
* What other context exists? Is this in the context of an actual play session with an actual world? Or an abstract "here's the concept of a UWP, don't worry about the details"
* What do you want them to be able to do without the reference handy when faced with a UWP in the future?
* If you can only provide one example, use contemporary (21st Century) Earth (B867979-8 - or thereabouts). If you can provide some other examples that might be handy. Perhaps a UWP and capsule description.

IMHO, in order of importance to learn:
* The order, which is why MWM highlights the
StSAHPGL-T pattern.
* Then: Starport codes which are a simple scale (ABCDEX)
* Then the idea of eHex, and that most fields are a scale: S/A/H/P/L/T
* > A is usually "exotic"
* G is an outlier, get used to looking it up
