What is so difficult about recording the number of flights separately?
As far as my logbook goes I am a bit ADHD and if I fly two different aircraft of the same type I like to record that so that should I need to refer to which part of the 2:25 I was flying G-ABCD it is easy to do so. Not sure about logging the 25minutes ‘parked’ as flight time or block time for that matter - “from the time it first moves under its own power for the purpose of flight to the time the brakes are applied at the end of the flight.”
