I am a cover driver and had an orion guy ride with me to map the route. He brought his little tablet with him so we had the GPS turn by turn solution. I was amazed at how many times the solution had us doing a complete 180. "It has us turning around here". REALLY? we sometimes were half way through a coldisac with a nice open a spot to turn around a quarter mile ahead. I told him so many times I don't feel comfortable doing that. He understood because he used to be an on car.
Anyway the day ends and we were 7 miles over the solution but had a 97 percent compliance. Had construction and one piece that wasn't in board we had to go back for. He told me he would put that in his notes. Hope the poor guy didn't get canned.
Orion can be a good tool for a guy like me who doesn't know too many routes that well but it should be used as such. Not the end all be all for the way a route should be run. Veterans on their routes can kill Orion by not following it for sure.
