I disagree with this idea.

TB members are voted in to their position. People can vote for members for whatever reasons they want.

How many nights someone was away from home in the last year only tells me how many nights someone was away from home in the last year. It doesn't tell me they are reasonable. It doesn't tell me what they believe in. It doesn't tell me how they look at certain issues. It doesn't tell me anything that is important to me with respect to who is representing me on TB.
