You probable could do worse then his formula, but it basically recommends what someone trying to get the most would run anyways, and seen no evidence that being 1-4 wider is a huge loss and tighter seems generally to be a gain and he talks it up as 30-50 tq+ gain by following him, the only gains I've seen like that is when people are wider by 6-12*.
To me it's like this, say I said I came up with a formula for street strip cam duration , and said it was the **** you couldn't do no better then to follow it and it generally recommended cams in the 235-255 range basically what people generally pick for street strip and cause those are the cams people generally want and the performance is obviously generally good then I say see I told ya my formula is the ****, that's what I'm kind of seeing here.
