I checked out your post on cdfreaks regarding slow vs. high-speed burning. Interestingly, I just purchased some Fujifilm (TY) discs at Target -- unfortunately, there is no speed rating on the packaging or the discs (the labeling just says "80 min. audio CD-R" so I have no idea what their rating is). Why doesn't Fujifilm label the speed rating of these discs? Anyway, I burned one of the TY discs at 16x and performed a KProbe test at max speed. The C1C2 report I received was extremely similar to the result you received for your TY disc (burned at 4x) except that my C1 numbers are slightly lower than yours across the board. I also got the same increase in C1s toward the outer part of the disc that you received. I was getting an average of 5.5 C1s with my Prodisc burns. These TY discs are much better:
Fuji (TY) 80min CD-R burned at 16x (52MAXX burner):
C1 Max= 9, Total= 1523, Average= 0.566
C2 Max= 0, Total= 0, Average= 0.000
Even though my TY discs are not labeled with a speed rating, my next project will be to burn a TY disc at 40x to see whether I get the lower number of C1s that you got when burning at 40x.
