AF Airlift Fixed Wing guy here. If the DA 759 is your Arrrrrrrrmy flight history record/printout, rely on that for all your mil time. Recruiters and interviewers know what to look for on mil history printouts, and it simplifies their review. It might be sound to total your mil time to one line in any bound Logbook, but it isn’t required. Log your civ time as you’ve already been doing.
Mil to civ conversions aren’t for logbooks, they are for applications, if directed by specific companies.
Don’t start “Making Easy Hard”. The Juice is not worth the Squeeze. That’s what the Arrrrrmy, and the Air Force, have been doing forever.
