Sticking it in your logbook makes you look a bit of a twonk in my opinion
Blackadder, don't show your logbook to Bose.
When I had about 200 hours, I had the use (after midnight) of a DC-8-63 full motion simulator when I worked for the airline. I read the flight manual, and taught myself to fly it. 50 some hours of IFR flying in it, every landing successful (I did not know how to "fix" an off runway landing, so better no to make one).
All that time is in my logbook, with zeros, and the "time" flown in the comments column. No one has ever had a problem with that, it represents my flying experience, I'm just not claiming any credit for it. I'm sure that if I ever begin to get old, I'll look back at those entries with fond recollection - when my memory is not so effective.
It's your logbook, enter what you want.
But, only take
credit where you are legitimately
entitled to.
