CAV 16x Speed The Pioneer 109 managed a burn up to the 16x maximum in 5min 58sec

CAV 16x Speed The NEC ND3520AW reached 16X burn in 5min.58sec

PI start about 10 and gradually increasing up to a peak of 224 at the end just a little high (but within the accepted maximum I allow of about 300)
Jitter steady increase between 10% & 15% with an average of 12% good result here
PIF apart from the 2 minor spikes of 19 it is virtually non existent

PI apart from the one spike of 119 it reaches a maximum about 80. A good result
Jitter is fairly constant and remains in the 10% - 15% range
PIF is virtually nil

P-CAV increase from 6x to 12x speed which is the maximum I could get.
Later firmwares only reached 8X maximum

CLV at 4x speed

PI 20 - 84 with no large fluctuations a good scan
Jitter good results here average 11%
PIF virtually non existent

PI Peaks at just over 100 which is good especially for a 4x drive on 16x media
Jitter Very good averaging 10.2%
PIF next to nothing

Some fluctuations after 3.5gig but no errors. 8x burn with later firmware produced a perfect graph click graph to see

A few minor fluctuations to an otherwise perfect scan
