My guess on these shops is that they don't have to have all of the locations done--or at least not every month. They don't seem to be aggressively bonusing them. I see $3 or $5 and I'm told they can't go any higher than that. And they're still sitting there on the last day of the month with that $3 or $5 bonus. Therefore, my guess is that there's no huge necessity to get them all done by certain date. I did several in southern California with a $5 bonus. I got lucky and didn't have to wait on an employee. I found the route to be reasonably lucrative and not too bad. Once you download the timestamp camera app it's really not that big a deal; you just take the picture and download it.
The fluctuating rate of base pay leads me to believe that there is only a certain percentage of locations that have to be done. Perhaps they adjust the base pay based on how many locations got done the previous month. There is a possibility that at some point every location has to be done, and they might have more aggressively bonus certain locations at the end of a deadline. But we will see. When I was doing the wireless health and safety audits on presto, locations that had not been done in three or four months were paying $70. I can only hope we get to that point with this project.
Also, I've been doing some shipping inquiry mystery shops, and ipsos is asking for a timestamp/location-stamp photo on those as well. It would not surprise me if eventually the timestamp/location-stamp photo becomes standard.
