Suggestion to Improve Rating Stability

As I understand it, chess.com uses the Glicko formula for chess ratings. One of the flaws (IMO) with this formula is the built in assumption that strength falls off as the player becomes less active. Activity however is relative. I may choose to play unrated chess and keep active and hence the assumption made by the formula is unreliable. The K factor increases as time passes between rated games.

You're right. But it's difficult either way. The assumption that strength remains unchanged after inactivity is also unreliable.

Posting one copy of a thread is sufficient:

lol - I didn't  - I think the Android app did it when it hiccuped.   :-)

Cheating is also a factor.Unfortunately chess.com banned the cheaters list,a big mistake in my opinion.But that is another discussion..
