I've had another look at the thread.
(I don't use that forum much any more - it's no longer the good calibration forum it once was as it is now chasing cash, and is not 'for the users'. Have you noticed the number of posters that used to provide good information are no longer there... I see DeWayne Davis (D-Nice) has been banned!).What ColorCal has said regarding the 0.333, 0.333 xy readings is correct.
It certainly appears Matthew Smith (Dark-007) is deliberately posting marketing hype, rather than valid info.
But that's no surprise when he is paid by Calman's marketing manager, as has been pointed out in that thread...
