That would not work either, since that rating would be based on the game and not the player. It takes two to play and if you are an actual frequent mover and your partner in that game is not, you will get a rating based on that players rate as well, not just yours.
If I average 6 moves a game per day, but the guy I play averages 1 move a week and it t ...[text shortened]... e moves per day per game, which was 6, so instead of a 24 week game, it would show a 4 day game.
Based on that logic all our player ratings are rubbish too?
Just like a rating value, a metric on average game length is never 'exact' - it's a snapshot of a moving target.
And as you say - your moves can only be made when it's your turn, so if I exclusively play slow players then my own move frequency will also be slow even though I may be itching move all the time.
Game length seems better than move frequency as within a single game move frequency varies a lot all depending on the context of the game - this is my experience anyway.
An average game lasts about 40 moves.
If I'm playing a 3 day timeout game I should be expecting my opponent to take the full timeout - their move time is therefore about 120 days + whatever timebank is in force.
I'd find it far more useful to know my opponent finished 3 day timeout games on average in 30 days as opposed to knowing they averaged 4.5 moves a day.
The 4.5 moves per day figure has no meaning in the context of the game I'll be playing as it depends on the number of games in progress and the timecontrols being played.
The game finished in 30 days could be compared to my own figure to know if I'm slower / faster than the other player. A much more useful figure all round.
However - I'm against this being implemented as it's not
that useful and would
a) take precious coding time to realise properly [the calculation may be simple, but it has to be put on the page and space made in the database to hold it etc. etc] and
b) It would add that little bit more load to the server to calculate - all these little bits add up to a significant amount when you look at the number of games / users there are here.
