I updated the spreadsheet (https://docs.google.com/spreadsheets/d/1DtGrPEckX8y-2-zAFwUgzqCo4HYwUctZNOKDLbYD4Vk/edit#gid=471313666) with azimuth between two 12-minute checkins. Records are sequential by time, and for Kansas you can look for "back-tracking" by scanning through the corresponding records where azimuth is between 225 and 315 (That's a 90 degree slice that will easily get any eastward movement).
You can cross-reference these dates/locations with the team1.kml pastebin that noobrunner posted initially (http://pastebin.com/qqeK8RL1).
There's also been a long-term high-frequency update that a ulister has going based on their live data.
I locked the spreadsheet so no edits can be made.
Looks like a westward backtrack started around at Jun 5 at 12:38am Eastern and continued til at least 1:02am covering at least 12km. Looks like they went almost all the way back to the outskirts of Emporia before turning around to head east again.
Thanks, that is great.
So you are saying that Robert ran only 1190 miles until 6/10/16?
It all looks pretty weird to me.
Doesn't sound right, that was the day of the TomTOm screenshots and I got 1448 miles out of them.
