Efficiency
As a coach, what I LOVE to see is someone sticking to the conservative game plan and saying after that they should've gone faster. This allows them to be able to attack the WOD again with confidence and knowing exactly what they can do as far as output. Then possibly cranking it up at the end and even surprising themselves. However, most people do the exact opposite, and come out hard and then fall off around the 50-burpee mark. The result is a longer and more painful WOD.
