Same disc + different drive = different disc quality results?

Can anyone explain why the different disc quality results of the same disc with the three different drives?

I don’t expect the exact same results, but are the differences between the iHAS122, DRW-24B3ST and LH-20A1S justified?

The disc was burned with the iHAS122 at 12x with Smart Burn enabled.

Perfectly normal. And the best is: you do not know what drive is “right” here.
Consumer drives are not what could be remotely considered as precision instruments. What you see, is how your drives can read the disc inserted.

Here are two disc quality results with the SAME drive of the SAME disc.

The quality score is the same, but the PI Errors are different in the two scans.

Shouldn’t the results be the same when scanning the same disc with the same drive?
