Yup! Wind test the desired motor section, only because it was the way I was taught and thought everyone else determined maximum torque/winds/weight. Start with a short piece that "always" yields more turns at break than break winds for the full size piece. (For me, full size motors break at fewer average winds than the test.) Then, back off 10% for the launch torque and hope everything stays together through launch. Really scientific.
Winds testing for calculating energy - and graphing - was a fantastic lesson in showing how flight is achieved.
