Do ELO rankings include inactive players ?

To be more specific, this is Silene's last Tichu game https://boardgamearena.com/table?table=565881944 It was Sep. 22nd, she had 358 elo. In the current Tichu ranking, the 17th player has 363 and the 18th player has 346.

Interesting. So a player retains their ELO score but the top 100 ranking indicator and their place in the “all time” list gets removed, presumable until they play again.

I read also that ELO above 300 will deteriorate slowly over time for a player no longer active in that game but I’m not sure if it was implemented by BGA.

All forms of ELO decay have been rabidly opposed and none have been implemented as far as I know. Of course, rabid opposition alone does not always matter.
