I still disagree. Not totally fruitless as the cup is 4.25 inches wide you will still get a better idea of the break thru practice.
*edit* On third thought.....
For courses with two pins....Other than on the 1st or 10th hole where in practice mode you can restart to get the correct pin, it is a lot of trouble and time to do so on the following holes. It's still practical IMO to get a good idea of the break of a putt via practice for the many courses with only one pin.
