Here is API SN to SP
It’s official. Like modern engines, motor oil has become complicated. Beginning on May 1, 2020, the International Lubricant Specification Advisory Committee will start licensed sales of GF-6, the next generation passenger vehicle motor oil standard. It’s time to begin preparing now...

Notice your spider has 7 levels to reach and if the scale is the same 2 makes it to 10
SP has 15 levels to reach and 4 are over than 10 on the scale.
But I have heard that same thing… However they were applying that stuff to SN, not SP. Notice they say 2015. VW 504 works for Europe and they have different requirements, like long OCI.
You see It is what you read from your source. Personally
I would not trust your source…
Lubrizol is one of the main additive package manufacturers used by many major brands that aren't Shell/XOM (because they co-own Infineum).
The Lubrizol relative performance tool (what that screen cap is from) is designed to show the different emphasis placed on those categories for the different specs. It is not designed to compare specifications between brands (so LL-01 emphasis on deposit formation can't be directly compared to DEXOS on deposit formation) but it gives you an idea of the focus made by manufacturers or bodies on those areas.
The API approvals are the "foundational" approvals for North American manufacturers. That is, an oil starts with API SP for example, and then the manufacturer's own criteria are added on top. This is how we get the Chrysler MS specs, Ford WSS-xx specs, GM DEXOS...etc, all of which are more stringent than the basic API approval.
The Euro marques go much further still with far more extensive protocols and much stricter limits. The Afton Chemical Handbook is a good place to start if you'd like to see what some of these approvals involve.
Porsche A40, as
@bbhero noted, includes extensive simulated lapping of the Nürburgring and many other tests, followed by a complete engine teardown with measurements. You can find the entire protocol, and a video, if you search my username and A40 on this site.
