It's a Steibek Curve. You guys will actually find it on Google.
And the entire issue here has to do with the VVEL and it's extreme lubrication requirements. So unless every high-performance engine old guy has owned in the past was running a similar setup as a VQ37VHR with VVEL, I don't get the point. 220 won't kill your engine, but the oil clearly loses viscosity to where it is below the manufacturers specification.
It's the same reason Nissan markets it's Ester Oil. It is for it's friction properties specifically for lubricating the VVEL.
