Each person has their own way of thinking what a safe pass is and is not. I for one would not have had a problem with either of the passes that you mentioned, but that is me and that is why I got into racing. I don't get spooked too easy anymore. I am probably one of the nicest passers in track days and racing but I have done what you have mentioned a few times. Especially against liter bikes when I am on my 600. These situations happen when the closing speed is high. I have only had one person come up to me about a pass and it was someone riding in Advanced at Putnam that should have been in Intermediate. I apologized and just went about my own business not changing a thing instead of trying to tell him his riding was the main reason for the close pass. I was the passer, he was the passe, and I was responsible for the safe clean pass(which it was).
