Changed cochran_comander_profile_size function parameters

Browse Source 
This function is much more useful if it works like a
ringbuffer_distance() function. It assumed the wrong values when
calculating profile size and it didn't have easy access to values it
needed to properly calculate profile sizes.

It makes sense to keep since it validates pointers.
