I have the old i1 but I still don’t DC every ten minutes, give me a break! I usually do it a few times, but if I am certain to DC before I make my final tweaks and take my final post cal that measures and looks great, …what difference does it make whether I followed that cumbersome suggestion repeatedly throughout the process? Perhaps X-rite doesn’t want a user to depend on readings beyond 10 minutes but I am NOT DEPENDING on the readings until I take my FINAL POST CAL. Is there any data on how much the old i1 actually drifts at 30 mins…my experience would suggest not very much . …certainly good enough for getting everything GENERALLY lined up and ready for the a final Dark calibration/finishing touches and post calibration. IMHO
