I read that he believes he has found a method for finding exact tempos for every work bach composed, I haven't seen his work praised by anyone else so I suppose they aren't widely accepted, but then I haven't really seen anyone say anything about them. Right away I asked myself why Bach himself would have never written or said anything about such a method of devising exact tempo for his works if he wanted them to be performed in just that way though, anyway I was just hoping to hear the opinions of people who have perhaps looked over them in more detail.
