What I'd personally like to know is what makes the ST50 show 16ms on a timer but 47ms on the lag device. That's a very sizable gap. Obviously we know the S2 and ST30 also showed a number of 16ms results on a timer, but apparently only 30ms on the lag device. I'm wondering if perhaps the sites somehow botched their ST50 readings (e.g. only took one shot), swapped GPU brands, or if video drivers have gotten worse in the past year or two. Is it also possible that a change in the way the panels draw their image could result in different values against the photoeye? Has anyone found an exhaustive multi-shot timer test (e.g. thepoohcontinium's ST30 in the OP) on a 2012 model?
