Not sure how I got in the conversation,but a friend and myself were talking about this the other day.Turns out he hold the tiolet paper with his thumb Is that possible??Do you just teeter it atop your thumb in hopes for the best??
If I still had a shitter in my bedroom (I had to take it out) I'd set up the camera so you could watch how I do it.
Mabey your friend will let you practice on him if he's so good at it.
