Nice work dude and I feel this indeed contributes significantly to the longevity study....
However, you above all others should know the concept of parity and jitter are largely meaningless in terms of "best" burns. It's not a resultant that can be used to ultimately determine overall quality of media, nor the disc.
Parity and jitter and pretty graphs are all well and good - but the more serious metrics we should look to (which our AudioDev homies are) are things like media geometry and reflective index measurement.
I'll never go as far to say a disc is the "best" I've seen, based upon the measurements you have used, alone.
All the same - nice work bastid.
