I bid routes based on the areas they deliver to, the pickups, the trucks they are in, and the general attitudes of the regular customers on those routes. The time allowances, miles, average over/under, average paid day, and anything else that is mostly determined by the the driver currently on those routes, are not a factor for me. Because after I am on a route long enough the bean counters will eventually have to adjust the route and/or workload to my speed and habits as the driver. That or end up paying me allot of extra coin in addition to having to answer for my horrible "numbers" to a coward on a conference call. I guess that's why I could care less about peaking at other people's stats.
Bonus is like a disease. It, mostly due to the bad habits of bonus babies, destroys routes. But to mention the other problems that have been discussed here. And others that have not. I honestly wish the union would get rid of it.
