Danny,
TP says they took an SMC pack that had the following on the box (from your GFX):
537 - 7.43 - 5.4
and got this on their GFX
529 - 7.38 - 6.8.
Clearly, that's much less favorable numbers than your own GFX produced. Then, on the same unit they tested their pack, and got
507 - 7.44 - 5.7
That tells me that your GFX measures things much higher than TP's GFX. So, it stands to reason that a TP on your GFX would also be higher, since they're being compared on the same units.
Yet, when you measured the TP pack, surprisingly, it's much lower than what TP got, rather than higher, as you'd expect.
514 - 7.40 -6.5
So what's going on? Which one of you guys has the magical GFX that makes your own stuff look more favorable than the other guy's?
