Lorelei (specific HAA legal ruling by the way) confirms that the 14 hour rule is a planning except for thone circumstances outside of control. it clearly states "reasoanbly antcicpate" conclusion of the flight assignment within the 14 hour "duty period." Do you have a duty day limit if you don't fly? of course. Without debate. So stop trying to mix the two incorrectly. Your duty period is based on your restraint from the certificate holder and when your rest period starts and ends. Any directive including admin, post flight, etc are directives and is considered part of your duty period by the FAA, so it has to be included in planning. You are so off it's crazy.

No one said you can't fly part 91 Without the crew, but you are still under the part 135 duty period you reported for and have yet to be properly released from and therefore must comply with duty period rules under 135. 

of your operator (assuming AMC) states you must comply with 135 rules for all legs of the flight, why would there be this magical exemption for duty time only. Hmmmm....
