I would say this is accurate..

Normally in warm weather the damper should be open to help keep the chimney drafting. Sounds like your chimney is drafting well
but like fastcat said, without a manometer permanently installed its just a wild guess. And the Carbon Monoxide detectors like he suggested are a must have.

No, actually a consistent draft between a .02" WC and a .04" WC is perfect.
