Would like to know the reasoning behind adding SAE correction on a engine that, according to what BMW have told us, is capable of correcting itself for "non SAE" conditions... You just can't add SAE correction if the engine already has corrected for the "non SAE" conditions!
I'd say the case isn't closed quite yet. Just in the SAE corrections that has been done here, there is potentially a substantial error in the claimed "facts"!
As you said; Garbage in, Garbage out...
