Yes, the TFP article is strictly about what GF could've done better to improve it, targeted at readers that are, for the most part, already familiar with it.
In the one I'm currently reserving here I was planning on writing a complete guide on how it works in the actual games: the booths, the coins, the castle, the level ups, the missions, the Battle Agency etc, aimed at readers that might still be new to Gen 7 for example. I already have a draft in mind and I'll get started as soon as I receive the approval!
