For the speed, the fastest you read something, the more you may have error, like jitter correction on audio track is more active, and as the speed increase, the algorithm can't think out the box, so it forces interpolations to keep a constant bitrate.
Erm, no, you're misunderstanding the reading process. Interpolation only appears on hardware CD-players (when you're listening to the music), not when you read the data digitally, sector by sector. It is either copied properly (0 C2 errors) or not (>0 C2 errors).

Ah ok ! When I dump PSX games a long time ago I had to disabled the jittering process in order to have raw datas, and not corrected one. The best method was the Disc at Once to avoid those problems but some CD couldn't be copied in DAO. 
I thought by default the datas were corrected so my bad !

It would stay a mystery indeed for our brushes indeed ^^

https://redump.info/disc/49823/ -- dumped nicely the same way, the layout is a little more bizzare.
