I wanted to write an interesting possibly DEADLY consequence of appending run data to a previously recorded run
The Scene is the beautiful Blue Mountains west of Sydney Australia a place of many many cliffs
Bill Philips is doing the tourist thing and decides to track a run in the bushland on the top of the escarpment
Later Bill stops tracking his run
Then not long after Bill resumes tracking his run and appending run data 100M down the track
A year later Bill Philips visits the same location and thinks that he will do that run again
The track is a little overgrown since his last visit and Bill is finding it hard to pick his way through
Bill ended up at the place where he stopped tracking and his device is pointing him to where he resumed tracking.
Bill thinks he as found the path heading to where he resumed tracking
But instead Bill finds the edge of the cliff which he promptly falls off and Bill is never seen since
so you could say that Bill was killed by his own app
You may think that this is a far fetched story but in the Blue Mountains tourists wandering off the edge of the cliff
is not an uncommon event because in places the vegetation hides the edge of the cliff, I know of one case of a geo-cacher who was led off a cliff by his GPS.
so really this kind of feature /bug can be VERY DANGEROUS
