Thanks to MK2's advice, my results have gotten better. Now my claim percentage is in the mid 70's for kills on friendly side of the lines. I've had 3 kills confirmed so far, but only on missions with 1 kill. Multi kill mssions have been rejected so far. Other coments regarding claims, the ingame map is a bear for reading city names and does not appear to list Airstrip names so ... kind of tough to expect that info in a claim report. Not to mention, the names of your flight members and wingmen are tough to read too.
But, as I've said before I love the combat. In a Pup I had a D3 blow to pieces after a long burst with a leading shot. The plane exploded so bad, pieces of the wings flew into my wings and crippled one wing and stalled the engine. A field nearby was a lucky landing spot. Loved it.
