Rusty,
If your claiming that lobe center angle is between the intake and exhaust, then it would be called "centers" angle.
"Centers" ,Plural, because it's referencing two lobes in the equation.
But it's called "Center angle" ,Singular, because it's only referencing one lobe.
But why should I care, I'm not payed to educate here.
