OK, thanks to all the above advice, I finally got all devices to work for two consecutive short runs
AND uploaded (i.e. Stopwatch, Runscribe, Stryd). The 'stop rS' using canceled sync works GREAT!
As planned one run was attempted midfoot landing, and the other was
forefoot (up on the balls of my feet, no heel touch).
See summary of results below and screenshots for addtional data.
Link to run if you are interested is:
Stopwatch was the primary timing device & was clicked on cue. Others were picked off graph with endpoints
as close as possible to estimted stopwatch start/stop points.
Shoes:early model NB Minimus Trail Zero's (zero drop)
On the midfoot stretch, I was trying hard to focus on landing with shin upright and feeling a square foot landing.
On the forefoot stretch, I was trying to land squarely on the ball of the foot every step and did. I do not
have calves of steel, and could feel the heels dip down everytime after impact however they (almost) never touched
Since most of my other rS run records show footstrikes of 12-13 for BOTH feet, it's clear that I affected the
gait by intention, and that rS picked it up. But I am not sure what it's telling me about my footstrike.
Does not appear that forefoot strike on right foot was detected. Why might that be?
runScribe reported pace was a little fast, could be reduced by calibration. Normal running gait on this
same road results in accurate pace reporting. Agrees fairly well with Stryd GPS based pace report.
cadence report also agrees between the two devices.
Flight ratio was higher for forefoot strike, which seems reasonable - there was more 'launch'.
Stryd wattage indicates that possibly (I take all this with a grain of salt) it cost me
more energy to make that launch than I saved by being in the air instead of on the ground.
That's the report. Have to think about what to try next. Other experimental results and/or comments are
