Gates belt theroy questions
After using the WCP belt calculator and learning the math behind it from the Gates belt theroy book I found on discrepancy that caught my attention. The calculations were for a HTD 5 180 tooth timing belt between two 24 tooth pulleys.

The math that I ended up with using the math in the Gates theroy book was:
pitch*(Belt teeth - pulley teeth)/2 = c to c distance
5mm*(180t-24t)/2 = 390mm

The under lying equation from WCP seemed to be:
pitch*(Belt teeth - pulley teeth)/2 +0.001"= c to c distance

So my question is what is the point of that extra .001" added to the distance?
