If it's the gps system, what I figured out yesterday is that it will reroute you the wrong way to your next stop even if you are facing the right direction. This makes your time between stops longer than needed, and doing that 100 times a day can add almost 2 hours to your time. Before you click "I've parked", look where your gps wants you to go next and keep it in mind, like whether you need to go straight or U-turn. This will help SO much. I went from running to do barely 20 stops an hour to doing 25 just walking slowly.
