Stop Count

So I've noticed the math on the stop counts don't usually add up, during my shift. Am I going crazy or is anyone else realizing this?

For example, I'll have 160 stops at the beginning of my route. Once I finish #80, I should have 80 stops left, right? Most of the time it'll say more than that....I've even stopped editing stops to see if I'm bugging out.

I'm always paying attention to what number I'm on, to make sure I'm at (or above) a specific number per hour. I treat it like a game to make it go by fast (lol). Is anyone else experiencing this?
