Rating differential

From what I could gather, chesscom uses the Glicko rating system. So far I wasn't able to find any way to see one's rating differential, which is why I'm wondering: is it possible to learn what your RD is on chesscom?

They used to show it in stats but they removed it last year without any explanation.

It was very helpful in explaining to new members why their ratings adjusted quickly. However, it was probably confusing a lot of people who had never studied statistics.

RD is "ratings deviation" and yeah, they removed it from profiles.

You can still access it with this link:

Thanks, that's what I was looking for

They removed the RD from Stats, but they still have support articles that haven't been updated to reflect that change, for example
