I was confused with the LOT theory too, you might not get to many replies from this thread, because the LOT theory has been discussed so many times, but here goes..
The LOT stands for Loss Of Tug, you probably know that though.
How to find out your LOT, well grab your penis under the glans, foreskin backwards or forwards it doesn’t really matter, then pull straight out not too hard but a decent amount of tug, now holding that grip tight, point your penis towards the roof, straight up, this is 12, make a kegel, this is when you squeeze your PC muscle, if you don’t know what these things are do a search on the forum. Now do you feel any tugback at 12? I’m guessing you do, quite a strong one at that, now go from 12 to 6 but SLOWLY and make sure you go on the right side don’t rotate left, just rotate your penis right and down to 6, make sure you kegel all the way down but VERY SLOWLY.
When you feel a CHANGE in tugback, no matter how small, as long as there is a change, that is the number you want to note, then round it off to the highest number, for instance if it changes between 9 and 8 call it 9.
This is how I do it anyway after much discussing with the man who came up with the theory.
If you have a LOT of 6, I think you are better of fulcrum hanging or OTS or SU. Lower the LOT then you are better off hanging at higher angles, if I’m not totally incorrect that is, I’m sure some others will give thier point of views, so sit tight.
