My dad's running stat

Background:

My dad always runs at the park behind our house, which is very popular with area runners. During every run he counts how many runners he passes as well as the number who pass him. This becomes a cumulative yearly total.

I won't go into all of his strategies for keeping this number favorable, but I will say that they are numerous and top secret.

I received this email from him yesterday.

Passes 164
Passed by 16
91.111111% passing rate.

This includes the disasterous day when 5 people (and a dog) passed me all at once.

I have not counted the dog in my final 2005 statistics.
