P are you sitting down? Hopefully not eating steak! OK the MSD tech said that when they made the video they activated an electronic retard box (mainly for Nitrous he said) which DOES change RP & they did that to show the bennie of their adjustable rotor to change RP as needed (which Joe changed in the pic) which is what we do slightly differently with redrilled reluctor roll pin holes. He did confirm that mechanical adv does NOT change RP
