It would be interesting to know how long it took to change from routes being paid according to mileage and to the current evaluated system. When I started as a sub the route I was on was paid based on the mileage and not on a mail count as long as the regular carrier stayed on that route. When he retired it changed to the hourly evaluated system. I wonder how long they had to work to come up with the time standards and to implement the current system? Probably not as long as it is taking with RRECS.
