Nobody here doubts your expertise Cliff, but since we don't do this for a living, we need the tools.
I totally agree that not getting hung up on the numbers and tuning for what the engine needs is critical.
Chasing a digital number on an AFR gauge (especially by taking the air cleaner on and off) is no way to get to a driveable condition. Set it up with the air cleaner on, verify timing is correct, and max vacuum is going to be really damn close to perfect. Maybe half a turn one way or another with it in gear.
