Note that Plextor scan above did not reached 16x. Also, Plextor 716A and NEC 3540 scan at 1ECC, while BenQ 1620 scans at 8ECC, so the standard max PIF are different, ie max PIF of 4 for 1ECC and 16 for 8ECC.
I think Fujifilm DVD+R 16x (PHILLIPS C16) is still best 16x DVD+R media found this moment http://club.cdfreaks.com/showpost.php?p=1018055&postcount=37
If you look deeper in this forum you will find lots of MCC004, TY02 or even TYG02 can get better result than the PHILIPSC16 in your link above. (sorry crossg).
