There was a final “twist” to my tale - as I had inadvertently recorded an additional 16 hours of “Work” between my normal shifts, and also opted to work an extra shift on the Sunday (double bubble - be rude not to …) I got another WTD infringement on the Sunday for exceeding 60 hours in a week 
I’d best hand my licence in, I think…
Last time…
I ballsed it up about four years ago, I managed to show something ridiculous like 103 hours of other duty instead of rest. Sure enough a week later, ‘can you sign an infringment form please?’
Never signed one before and never will.
Practise makes perfect.
It all comes off your wtd average
I am glad I am not the only one who doesn’t do manual entry or know how. Just never bothered.
