Can anyone explain why its a necessary requirement? My Breit chrono's are just the A7750 28,000 never an issue.
as naturally 7750s have seconds at 9, but AP ROOs have seconds at 12, so to shift seconds at 9 to 12, transfer gears are used, which are culprits to reliability of sec@12 7750s in AP ROOs...
