Many fine points have been made but I thought I'd add one I haven't heard yet.
The automated measurement hardware doesn't have to create problems with a lack of delay.
One of the benefits of it being automated is not only that it can perform calibration in the middle of the night, but also that (if your software allows it), you could set the delay for drying to 15 min, a hour, whatever.
That said, calibration is indeed very different that profiling and measuring outside the device after a user-handled delay may certainly be most effective for some.

Steve
