A quick update on this topic for which others might find useful.
Just had my first service today and mentioned the starting issues when I booked the car in.
Apparently Honda are aware of the long crank issue and there is a software update now available to rectify this problem.
The technician has assured me this will solve the issue and the car should start immediately at the first turn of the key.
I'm now going to have to get out of the habit of allowing all the warning lights to go out before starting the car.
