Not Ranked
Everything I have read indicates the startng point should be at the main jet size + 60 and then fine tune from there. Sometimes it is suggested to put the air corrector number close to the main in a "Race application" when the engine is constantly in an acceleration mode. (Road Race) My personal belief is that this allows the main systme to "come in" quicker, and at the same time richens the mixture considerably. I am no expert, as I am still dialing mine in. But in your case I think you will find some improvement by weakening the main system mixture. Keep an eye on the plugs while making significant changes. Does you engine pull hard at 3500 and up? What size engine? Seems like a lot of duration for that static compression ratio.
For comparison on my 289 Currently:
37 chokes
155 Main jet
200 air corrector
60 idle jet
100 idle air jet
50 squirters
55 bypass in float bowl
F7 tubes
I have a flutter (light miss) at 60MPH @ 2900 RPM I can hear it in the pipes. When I depress the throttle the least amount, miss disappears. I am on the hunt. I am thinking 110 idle air
PS: A change to F16 Tubes cured the light miss.
