PAL overscan dimensions

According to book, I am Error:

"On NTSC sets, up to eight pixels of the upper and lower borders of the PPU’s output are lost to overscan,
reducing its visible scanline count to 224. PAL sets lose a single upper scanline and two pixels on the left and right."

I have yet to find an emulator where the default overscan for PAL drops 2 columns of pixels on the left and right. Are the dimensions in that quote correct?

Edit: The wiki seems to suggest the same. I'm not sure why emulators are not doing this.

Because we only consciously noticed it in the past couple years, and puNES is the only first-class emulator to have seen significant development effort in that time.

To that end, I just checked the puNES 0.100 overscan settings. The defaults appear to be 8 for up, down and left and 9 for right for both NTSC and PAL as far as I can tell.

I only said that puNES is the only emulator that's been being developed at the right time for it to even be known as a difference on PAL sets.
