The maximum values can be a bit misleading, for example, on your scan, the Jitter maximum occurs right at the start of the disc and in my opinion can be ignored as the rest of the trace is pretty much flat. I often get a PIE spike right at the start of a scan, these I ignore.
If the maximum value for PIE/PIF/Jitter occurs later on or at the end of a scan, it's probably worth taking notice of.
For Jitter, average value is more important. For the BenQ 1620:
Average - approx 10% is probably as high as I would accept.
Maximum - approx 12% is ok for me.
The values for the BenQ 1640/50/55 may be different as they seem to give lower values on the same discs when scanned.
