Your scans show rising Jitter on all burns which is slightly worrying. There have been reports of sub-optimal FujiFilm-branded TY media, maybe you have been unlucky enough to have some of these discs. Even the disappointing T03 discs I have (TH001330) don't suffer from that kind of rising Jitter problem.
Too high Jitter leads to higher PIE, especially on less Jitter tolerant scanning drives like BenQ. I'm sure if you tried scanning such discs on a Lite-ON, the PIE mountain would magically disappear
Some people consider Jitter when it comes to grading wether a disc is good enough for their purposes, while others generally ignore it. I'm sure the discs you have burned will be fine for normal usage on Jitter tolerant devices as the PIF levels are perfectly acceptable.
A 16x Transfer Rate Test should confirm wether the discs are ok or not.
Trying some other types of disc on your burner would help diagnose if the problem only affects those FujiFilm discs.
