Correspondence Rating Bugs

This is probably well documented, but I'm curious about it. Correspondence ratings behave weirdly in many ways: the rating that is displayed during games is the rating you had when the game started, not your current rating; the rating change that shows on your "Activity" page is horribly inaccurate; and the highest and lowest achieved ratings aren't accurate either. Is fixing any of these things on the upcoming roadmap?

Can you say it shorter so I can understand.

The displayed rating is supposed to be the rating that you had when the game started. I can't find an example of the rating graph and highest/lowest ratings being incorrect, so could you link to an example?

My own profile will do. My current correspondence rating is 1910, but my highest is shown as 1901. Yesterday I won three correspondence games and my rating was around 1900, but it said I lost 193 points to hit 1615. Similar weird patterns happen every day.
