Below is my output. This was about the fourth try. Idle power, no flaps until I got down to maybe 200-300ft, then added flaps in about 3-5 second intervals per notch. Flared a stall after crossing the treshold. Used full brakes, and might have held the elevator in the stalling position (can't remember). Note that with stall my nose wheel touched simultaneously with the right main, the left trailing shortly. I'm not sure how to read the "sink rate" or "contact force" values. Did I break anything?
