BLM cells

I've done searching on BLM cells and can't seem to match up my experience with it. From what I'm reading, it sounds like it should be a table of cells kinda like VE where it is RPM and load based. Like this: http://www.gnttype.org/techarea/faq/BLMINT.html

I logged my 7730 $A1 and exported, sorted and graphed it on paper. RPM appears to have no effect on cell. As best I can tell, Cell 0 only shows at idle, Cell 1 is open throttle and Cell 2 is closed throttle.

Anyone know of a link with some more information?
