I have an update on this. I spoke to someone from Mobil (not their tech support) and basically it's a non issue IMO.
Put it this way, you are allowed to have up to 90 microns of wear under the Seq IVA. Without compromising anyone's credibility, let's just say Mobil 1 scored way below that. I was given a number and out of respect won't post it. So as bruce said, it's taking something like 20 ppm and comparing it to 10 ppm and saying that there was a 50% reduction in wear and therefore that oil provides 50% better protection. Kind of misleading, yet factual from a pure numbers standpoint.
More importantly, while I do believe Valvoline to be a very good oil, they fail to have an oil that meets the Corvette spec and Honda HTO-06 which says a lot more than their vague comparison of "4 x better wear".
