I was just curious why you came to that conclusion .... I have read up on plug reading but it is not as absolute today with ethanol etc.. I have had plugs that were bright white but the AFR was rich and I could smell the raw fuel. It makes a Dark Art even darker...lol
You can still get a good read on a plug with ethanol in the fuel. Be it e85 or e10 or whatever. The projected tip and what looks like the depth of your plug around the porcelain are what led to my conclusion.
