Thank you for the interesting comment and suggestion.
I had not put much thought into creating a cell phone app, as I assumed (or hoped) that there was already a suitable app available for collecting the data. I had not considered the disadvantage that the so-collected data would get marked implicitly as imported. I'll put more thought into this, now.
In the meantime, what apps have you found with 1-second resolution and good accuracy? Other users, and I, would value your recommendations.
