Ok, I'll translate:

Based on looking a random material, a Panasonic plasma will reach half brightness at 100,000 hours.

OK, that means that looking at part of a logo, bug, or banner at full brightness, they will, at best, fall to half brightness in about 20,000 hours (because they are probably assuming an 18% gray average).

Assuming a linear fate of burn, that means that you will get a very visible

5% burn difference between a bright bug and black bars in 1/10 of 20,000 hours or 2000 hours. That sounds about right for a type of set that has known burn-in problems.
