Your average rating is shown for each board size (9, 13, and 19) in each of the different time categories (lightning 
︎, standard ◴, and correspondence 
)
I completed two games that are of the standard time category and in my game history show the ◴ clock symbol, which should mean that it is classified as such, but when clicked on that category before playing the games it showed 198 games and after playing them it still showed 198 games.
I have learned that the time categories are not grouped in the obvious way you expect them to be based on how you would select the games to play them, which is not ideal. But this is one step further because the games are showing themselves as being a part of a time category for which they are not being counted.
