I strongly disagree with your position on the 100hrs. It's well known within the experienced calibration community that any drift that may occur within the 100hrs, if any, will not be noticable to the eye. You mention an online article, one that anyone could have written and with questionable experience on the matter. This author could mainly be spreading the same misinformation that he read elsewhere without ever calibrating at panel or evaluating his age-old methodology, etc etc... There's little reliability here.

These panels are designed differently than CRT technology which had a lot of drift. They aren't designed to make noticable changes within several hours of use. If you had your plasma calibrated upon purchase and you had it recalibrated 100 hours later and ended up with different results, I would question the reliability of the calibration equipment being used on your TV. What measuring device was your panel calibrated with? Most of the "inexpensive" gear will return different results in each calibration session. So, if you have it "touched up" in the next 100 hours, and every 100 hrs after that, you will again notice different results all plus or minus each other within the same ballpark numbers. And these differences shouldn't translate as anything notcable to the eye even though they make look fairly large and significant on a graph. On the other hand, more expensive gear - for the most part - is more precise and repeatable and should return very similar results providing all other things are equal in the evaluation. We are trying to set the record straight - the 100hrs just simply isn't true and it would be great to put this beast to rest!
