My tests with MCC004@MCC003 strategy swapping on my Pioneer 111 series drives showed that that basic PIE/PIF and Jitter were neutral (no better, no worse) for burn speeds up to 8x, but it got rid of a nasty jump in jitter and PIE/PIF for burn speeds 12x and higher on at least one drive.
This jump in jitter and PIE/PIF exists for many CD and DVD media on the 111 series at the point where DVD burn speed passes 8x in CAV and P-CAV burning for DVD and passes 24x speed for CD-R. The size of this jump differs between individual drives - on some drives it’s huge and on other drives hardly noticeable.
I have looked through my 111 series scans for this strategy swap, but unfortunately my saved scans with and without the strategy swap are for different firmware version which potentially confuses the comparison, so I have chosen not to post them (yet).
I haven’t yest tested this swap on my 112 series drive(s).
