StereoDude - These are great ideas and we really appreciate the feedback. I agree with you that individual user reviews are heavily flawed, because of the issues that you pointed out. As a statistical entity, on the other hand, they constitute powerful data, when they exist in sufficient numbers, and when they are analyzed using the right statistical tools. Many times we have analyzed ConsumerReports findings and seen them contradicted by massive numbers of reviews from their own users.
As a site, our premise at ConsumerPla.net is based on analyzing user reviews - that's what we do:-) We expect that the conclusions we drew based on the statistical analysis we did in our Blu Ray media guide will have excellent validity. But we love your ideas on repeated testing, and we would be glad to (a) report on it, and (b) do the heavy lifting on the statistical analysis if some trustworthy old-time users here on the forums were willing to take on the testing, i.e. ImgBurn a set of discs, and test them every 3 months.
We would love to see someone spearhead the effort. We would be ready to swing for the cost of the media: we would order the media, then dispatch a set to each committed user, whom we would ask to burn the sets, then read them every 3 months. Every 3 months, we would collate the results and do the analysis. Since this is a long term project, we would want (a) people who have been around the forums for a while and (b) people who are willing to be doing this for the next several years. Let's see if some are interested:-)
