Thank you Robert.
However, if Dora had an endurance of 80 minutes, and Emil of 75, then, bearing in mind higher cruising spead of Emil, the operational radius would depend on the portion of endurance needed to form up, and reserved for combat and safety margin.
It is surprising to me that, given the difference in weight and hp, the Dora has only 5 minutes on the Emil in endurance.
