I did another calculation based on Monty’s earlier post in this thread.
He said he hung on average 16lbs for 1 hour and 2lb for 8 hours per day.
Which comes out to 1920lb*min per day.
If you look at his stats he gained 2.25” in 14 months, or 420 days.
(1920*420)/2.25 = 358,400 to gain an inch.
So about 20% more lb hours than the previous estimate, although in the same ball park.
