i've come across it a few times, ill see if i can dig up and information on it for you
grr well the only graph i could find was posted by xrox on these fourms but his photobucket account is disabled or the image got removed. xrox is well known on here to provide some excelent scientific data on technical aspects of displays in the past and if hes still around i would love to have him jump in here and post the info he has on the subject.
off the top of my head though one of the places i heard this discussed in the past besides many of peoples experiences on here with older plasma's is an interview someone did of one of the former heads of Pioneer's R & D, they were of course discussing image retention and black rise on panasonic's and he stated that the wear rate of phosphors in plasma's was studied by them extensively in order to implement voltage rise adjustments to drive the pixels as the panel ages, this is actually the heart of the problem with Panasonic's 2009 models, they implemented the same voltage rise that pioneer did to extend the overall lifetime of the panel but they did so too rapidly and it caused two adverse effects increased T.I.R. and increased black levels, both of witch he implied would actually return to new TV levels once the phosphors in the effected sets wore down to their slow wear levels that occurs if i remember correctly around 2000-3000 hours of use.
it is well known though that all phosphors wear extremely rapidly when brand new, the same thing happens with light bulb's that use phosphors.
