The spreadsheet I mentioned earlier showing how EPID and CPID compare
when you add integral gain (KI!=0) can be viewed at:

The model used is based on Mark's example from:

http://cars.uchicago.edu/software/epidRecord.html#Problems

which provides an excellent explanation of why PID's should not be used
as proportional-only controllers.
