I don't know the right value either, right now I'm using 7 for PAL and 23 for NTSC because the NTSC color phase (23 - 33 = 350) does look good and comes out at around the same value when comparing with a screenshot. So, there must be some discrepancy with the PAL vs NTSC phases. It'd surprise me if they had used separate resistor banks for them, so it's maybe a chip bug. Or it could be some decoder hue related issue that only NTSC has? Also, PAL values usually are just phase shifted by 33 degrees, but orange seems to be off, so that could be a typo (in the NTSC column in this case, I suspect).
By the way, I was getting more like ~223-233 for green on my machine (maybe other colors were also different)...
