Some interesting side notes: although I've calibrated many VT25s, I've only measured the black level on 2 of them (black level measurement isn't necessary for calibration). I did not measure the black level on the VT25 that I compared with the ST30. One, the original VT25 that I reviewed, measured .01 fL. The second measured .005. They were different sizes, and it's possible one may have had more hours logged on it than the other. Panel size makes a difference with black level on some Samsungs, though I don't know about with Panasonics.
Also, some plasmas change a little after they've had test patterns displaying on the screen for a couple hours. That's why I try to run a scrolling bar for at least a few minutes, and then give the plasma a rest with a black screen for a few minutes before the reading.
