Board Game Arena

The question is: Why, in the list of partecipants in a tournament, some players have shown their Elo points, and some others not?!

I realise that they are shown in descending order, starting with the strongest player. But I cannot understand: is this a glitch?

The players that have ELO points shown are premium members. I don't know why this is the case, but it's a hidden benefit of being premium.

Probably old code from back when only premium members could see their elo. That prevented non premium to get access to their elo number by simply joining a tournament
