BLITZ CM LADDER, i vote for this change.

If technical solution is not realistic, an other solution would be to propose a vote to the members for what ranking system parameter they would like by default.

Bootie, if you think the ELO is vague, here is a proposal of a simple evaluating Player Value (PV). It is simple and balanced.
With this system, a player can reach the top of the ladder and can also down at the bottom. No position is nearly definitive.
It reflects at everytime the real potential of a player, and everybody has a chance to reach the top of the ladder.
Don't worry, i am not leading a revolution ! The debate is not to introduce it in the Blitz system. It is only a way to show you that many efficient and precise possibilities exist and could be an alternative at the "vague" ELO as you speak about.

cheers.
