I am getting 2 different values for 70mm and 200mm for my 70-200mm. Do I split the difference here? I believe it was something along the lines of -3 and +9 respectively.

I assume you used 5D2 or 7D?

It depends on your preference:

- average them,
- choose the focal length that you use most (long end or wide end) and stick with that number, or
- use the long end number as it's more critical with narrower DOF.

Cheers.
