I probably would have done the same as long as: no shots had been fired, OR, we weren't after the cut.
The first implies an easy mental mistake that facilitates fast play and that IS worth a lot to me in the first 2-3 rounds. The second I say because we're no longer at the casual level of play; I'm more competitive than that and I know I would hate myself for a good long time if I did it. I have done it and unless my opponent protests I live with my dial choice.
