Aparrently, not enought vote chess games are being played to give an accurate rating.
But, a ranking based on inaccurate rating is surely already better than one based on number of games played......
But better still, in my opinion, is to create a ladder system. If you beat a team higher up, you move up some, they move down some. The size of the movement determined by the relative positions on the ladder, I'm sure there are clever people out there who can devise an appropriate formula.
When I brought this up before, there were questions of where to fit current teams onto the ladder, well, we have to start somewhere, use the current ranking, it will soon sort itself out.
Obviously, new teams start at the bottom.
Currently, the leaderboard is skewed based upon how many games you have played. The better teams are teams that have played less games but win over 90% of them. With the rating list we would be able to see which team is really the best team.
