Concise description:
Some extra statistics on the profile page showing the average number of rounds a player's games last, whether the majority of their games are sequential or freestyle and if their main style is escalating, no cards or flat rate.
Specifics:
A players stats on the profile screen might look like...
Games played: 385
Win percentage: 27%
Points: 1690
Average game length: 48 rounds
Discipline: Freestyle, Escalating
This will improve the following aspects of the site:
Experienced players will be able to make an instant (and accurate) judgement of a player from just this information. I know we can already judge a fair amount from the information already provided such as likely style of play based on a comparison of win% to points, but now we would also be able to see all this extra information without having to map rank on jump over to gamefinder. It would certainly helpful for those without map rank.
I think this would be a small, simple change that would improve this site. I also think that if CC can already record win percentage, games played and points, it should be able to record this extra information too.
