I did a 7 mile run yesterday. I know I did because I ran a route I’ve run before, know how my body feels after 7 miles, know the routes and the landmarks to verify the distance.
My watch didn’t record a 7 mile run – apparently I only ran 5.82 miles.
If my job depended on me being recorded running 7 miles, I’d be feeling more than a bit miffed. Are you confident your learning technology isn’t coming up short?
