Current ELO display and FAQ is not clear enough to explain what is going on, thus creating a bunch of bug reports/suggestions.
Searching by 'rating' or 'ELO' lists so many reports without bug at all.
Even though there were a bug identifying the cause or exact problem is hard for users not knowing current ELO formula.

In these cases some of bugs are from display problem, not actual ELO calculation.
I didn't manually calculate all of them so I don't know whether all of them are mere display bugs or not though.
Anyway, adding a link to FAQ's ELO section in post-game ELO tooltip and editing the paragraph clearer will make users understand current ELO system better.
Current FAQ does not address multiplayer aspect of ELO fully.
Also, the reasoning for multiplayer adjustment [N/(2 * (N-1)) → (recommeded N)/(2 * (N-1))] is not explained at all.

In addition, many players don't recognize 'placement matches' in BGA.
In first 10 games K factor is tripled, and next 10 games it is doubled.
However new BGA players don't really know how this does work, and even seasoned players don't acknowledge this.
Adding a highlight or exclamation point next to ELO changes which applies by K-factor adjustment period will notify this easily to everyone after the game.
Explaining why this applies for only first 20 games in FAQ might help too.
I filed a report in bugs/suggestions too, so please upvote if you're interested in or agree: https://boardgamearena.com/bug?id=29568
