I'm certainly a member of the being wrong club ( according to my wife frequently) as well . I suspect you are right that you get optimum performance by variable timing of an engine . However the issue is does it really make a big difference in the Model A engine. We are playing with only 40 hp so even if it gives you an extra 10% that is only 4 hp.
Anecdotally before I brought the 34 I did about 10000 miles per year in my stock 1930 Phaeton and various other stock Model A's On trips I would cruise at 50-55 mph for hours on end with no problems -would slow down to drive through towns and even stop at lights without ever touching the advance and retard lever -all seemed good .
Yes Derek I could put a Model B dizzy in -but I would miss my lovely copper connectors to the plugs LOL
