I do not think it wrong to poll 10 players, but I would regard it impractical to require it of ACs or TDs. I do not think (correct me if I am wrong) you did this in the case at Brighton where you chaired an appeals committee for me, and I do not think you needed to, since it was so blindingly obvious that even one of the appellants had told me he agreed with the ruling. There is also the question of who belongs to the "class of players" in question, and one might argue that the winners of the pairs do not. I think I am probably a pretty close match for the players, being (I think) of the same rank and experience, and playing the methods in question with all my most regular partners.
