Perhaps, we can extrapolate/approximate the start with an annotation that says the before MLL is unknown. ?
How about posting the contrast ratio too ? before and after. and if the SD card update was done and/or a-board was replaced. Oh, wanted to add one more data point - Break-in done.
0.028? You're in the running for the worst! Sorry to hear it.
I'll add your info. to my chart for the next update. Don't forget # hours and meter brand...
There are already a number of single data-points in the chart, which I think are valuable as well. They're a little harder to find without the lines, but if you squint, you'll see them. Yours will be in there next time 'round. I think the chart clearly shows that for those who measured at 0 hours, the level is exactly what D-Nice indicated, around 0.005 to 0.008 for Neo-PDP panels (likely higher for the X1 and such). We can extrapolate and make some basic assumptions for those panels we don't have 0-hour measurements for.
Just having "after" measurements is helpful as it adds to the credibility of the rise, since we can say with fair confidence where the sets started out at.
Contrast ratio: I think this is an important number that hasn't been discussed enough, especially since it's a figure that's actively marketed by Panasonic. Unfortunately, not many people have listed theirs in postings. It may be a better subject for a separate thread or at least a separate document.
Talk of A-Boards, Firmware version, Break-in procedure... etc: This is really getting into a level of detail that can be hard to keep accurate and useful. Unlike the data clearly showing a general rise in black levels, nobody seems to have any indications that it's tied to or affected by these things. I'm not going to say it's unimportant to keep track of, just that it's not something I am personally ready to tackle. I hope you understand. Anybody else wants to take it on... PM me.
