I think 5 to 10 min would be ok, time to get something to drink or visit the john.
It would also help to cool down after a intense fight, delegating planning back to the brain
Then it would also make sense to conserve ones engine, to make faults less likeable.
Of course refly then can only happen, when the plane is lost on or over own territory.
If the pilot is mia, kia or pow, the statistics must be set to zero.
My thoughts.
