i'm not really aiming for mine to be quite like the one you pointed out plus, but you're correct; many if not most of the contributors right now are doing these terribly. i was told that we were targeting these at new battlers who were seeing x pokemon for the first time and needed a quick summary. mine follow a pretty simple formula: a sentence or two of what it does, a bit of what moves and items it typically uses, and a two or three lines of how you can deal with it. for example
Ability: Volt Absorb
Base Stats: 65 HP / 65 Atk / 60 Def / 110 SpA / 95 SpD / 130 Spe
Jolteon has a top-tier Speed stat and excellent Special Attack, which, when boosted by Life Orb or Choice Specs, makes Jolteon a serious threat. STAB Thunderbolt hits very hard and is Jolteon's primary attack. As threatening as Jolteon is, his movepool is very small and predictable: his other moves are generally limited to Shadow Ball, Signal Beam, and Hidden Power Ice or Grass. Some Jolteon will use Charge Beam to boost their Special Attack and Baton Pass to escape from danger and to scout. If you have Blissey, or to a lesser extent, Snorlax, Jolteon should be easily manageable. Jolteon can also be checked by Ground types with Priority or a Choice Scarf, like Colossoil, Mamoswine and Flygon. If Jolteon is a problem for your team, keep in mind that it has a hard time switching into any attack that isn't Electric-typed.
this system has been working well for me, and i think some of the other writers that are currently having a hard time should try it ^_^
