IIRC Air Force rules allow you to add 0.1 for taxi-out and 0.1 for taxi-in. Or is it you can add 0.3 total? I forgot.
Optional; not required. I added some early in my career; later, I didn't.
So, if it was added into his AF records, he's good.....no conflict for an application.
JD: if it ISN'T in your AF records, make it so. You can make changes to records, but it is laborious. Talk to the Flight Records folks.
