Nobody will give you a hard time for not being fit for duty for a full pseudo-RAP following delayed report times. I believe the theory behind it is being able to get back to sleep following the notification (and acknowledgement) but understanding that the interrupted rest wont be the same as if it was outside of 10 hours. Obviously not everyone is able to go back to sleep in these circumstances.
