1105 to 1603 is 5 hrs minus 2 minutes which indicates correct to dry tanks.
4 hrs is the maximum safe flight time at 70% pwr with reserves from memory 29 inch man 2400 rpm!
His estimated flight time was 4 hrs 10 mins on the limit with reserves
Looks like they took the still air time for the route and totally ignored any headwind component or long range cruise setting.
Thanks for transilation assistance
