I think you guys may be way overthinking this. Carburetors are not perfect. If they were, nobody would have spent the money to develope EFI. If you are going to agonize over every data point then you need EFI instead of a carb and you can expect to spend many hours tuning it to get the perfection you are shooting for.

In theory, there is no difference between theory and practice. In practice, there is.
