18 rounds. Whoa! Last time I did this (a month ago, April 25), I only got 16 rounds + 5 pull-ups.
What happened? I took Kitch's advice and started off slow - a round at the top of every minute, rather than back-to-back rounds. I failed on the 10th round, and I felt like I was doing pretty slow rounds for the rest of the workout, but apparently not all that slow. Sweet!
(Still doing jumping pull-ups of course...)
