If nothing else the forum topic linked can be updated upon each data pack, and once enough meta-changing cards are released, a new updated primer can be posted.
I think in order to ensure the best quality for each primer, it should be done as a collaboration amongst the original author and whomever SneakySly deems suited, so that each build gets the attention it needs and the perspectives are as diverse as possible. I've met a couple players whose insight I respect and I'd like to have them weigh in on my observations anyways. Additionally, the authors need to be extremely good at all of the opposing factions, so as to address their article from the standpoint of eliminating weaknesses.
For my Jinteki article, I intend to play 50 to 150 games with each of the four basic builds, graphing the win rates over time, and rating each build in respect to one another. Though this is dependent upon how long such a task would take, and there are variables in such an experiment (such as the meta shifting, my personal proficiency with particular builds, etc).
