It is that 'adjustment' factor for the skill level of partners and the opponents that worries me. BBO Skill 2.0 tries the same thing. It seems to work OK for many players, but if their 'adjustment factor' is very large, you can ignore the result.
I know from experience what it is like to be the weakest player in a strong game. You are destined to go minus IMPs or minus dollars. You can try to make an 'adjustment' with a computer program, but I remain skeptical. It is even worse than computerized Power Rankings for college football teams.
Granted it may be a good marketing tool for many bridge pros. Still, how can you accurately distinguish between a hard-pressed pro dragging in a weak client in a quality field, versus one with a near-expert client playing in a weak field? Just trying ain't enuf. They need to be reasonably accurate.
Don't get me wrong, I like BBO Skill 2.0 and now use it to screen pick up partners for Speedball and other BBO pair games. Properly interpreted, it works very well. Before discovering BBO Skill 2.0 I had to laboriously analyze every player's recent hand records to separate the sheep from the goats.
