Not exactly clear on this, but why are we now required to write the bike's odometer reading on receipts when the photograph has to already clearly show it (the bike's odometer)? Also, referencing it on Google Maps? I can understand circling the date and time but not the others.
The receipt angle has been beat up, I'll take on the second half of the query...
As part of the questions asked in conjunction with an application, it does ask for which program(s) were used to determine the miles ridden.
Back in the olden days (like, before GMaps), you had off-line mapping (Microsoft S&T) as well as rudimentary on-line mapping (remember Mapquest?) sources.
In fact, I'd bet that there are still people out there that don't ride with a GPS on the bike. Therefore, they're thinking they have a SS1000 of 1022 miles, they mapped it out as 1012 miles, yet the bike had a uncalculated +4% odometer error. Oops.
This is a small group of motorcycle enthusiasts that help us all enjoy the pastime of long distance riding. It's probably in our best interest to do as much as possible (in lieu of doing as little as possible) while doing the ride to facilitate the process at the end of the ride.
