We didn't do a "poor job" of measuring input lag.
We reviewed the W1070 in early 2013 using the standard method of testing input lag at the time: a video source is connected to the projector and a reference monitor, then a timer is displayed and both screens are photographed.
For the past year, we have been using a dedicated Leo Bodnar input lag tester. It has consistently been giving us higher lag readings than the old two-screen method. When you're dealing with input lag, a faster testing system gives you "worse" results on the projector being tested, so that's not surprising.
By the time we got the Bodnar lag tester, we no longer had the W1070 in house, so we couldn't cross-check it. However, other projectors we checked using both methods revealed a discrepancy of about one frame, or ~17 milliseconds, on average, with the Bodnar tester reporting more lag than the two-screen method.
Since we measured 24 ms on the W1070 using the old method, the expected result for the W1070 with the Bodnar tester would be in the neighborhood of 41 ms. The HT1075 measured 49 ms.
I don't mind admitting when I've made a mistake, but this isn't one of those times.
