Energy transfer and capacitor ignition is different. Your diagram is of an energy transfer system. Easily recognised by the 5 wire stator which feeds the coils directly. Timing I believe is suited to the magnetic flux (and I’m going out of my depth)...

But capacitor and battery ignition are timed the same.
