KProbe question

I’ve got a horrific KProbe result (A3D2b) on a fairly cheap disk that suggests it should be a coaster, yet seems to play fine on my standalone DVD player (not watched all of it so far but not found a glitch yet). Another disk (T3b) playes fine until right at the end where it goes a bit haywire. Does this mean that I really don’t need to worry about the PI score, and should just be looking at P0?

That’s some really crappy media, I wouldn’t trust it. SCan it again at 1x speed and see how it looks.
