Sorry to be straight-forward, but you seem to be making a circular argument, like circular reference in Excel... You assume that 20i and 28i engines need to be differentiated hardware-wise, so that binning is necessary.
However I guess what I'm saying (and many others if I understand correctly) is that hardware-wise the 20i and 28i can be simply identical (save for the piston crown in the high CR version). BMW uses other software-controlled mechanism(s) to differentiate the two versions.
