I did it over the course of 3 days & took plenty of breaks. (The 14 hours does not include the breaks). I take down the plant & trim sequentially, as you did w/ yours.Your help would have been utilized. With 5 of us we spent about 7 hrs yesterday and another 3 hrs today. I can't imagine you having spent 14 hrs and by yourself!
I'm an ol' long distance hiker. It's never helpful to think about the entire length of journey when setting out. Just take each step, enjoy the process, take frequent breaks, and reach the goal.
50 person hours on trimming that one plant on yr end! Chop wood, carry water.
