Hye, it doesn't lose any frames as it is when the leader disengages the tone changes - so it is only how it's loaded at the start. Some cameras wind it of a couple of frames - or more - once the back is closed. I used to eke out 39, sometimes 40, frames on some cameras - especially good when it was prepaid slide film. Of course if it's going o the developing tank it's arguably better not to pull the film through the felt again anyway. It just annoys me that removing the end need a pair of pliers when there were perfectly good cassettes where it was easy to remove the ends.
A method I used for years before I finally broke down and bought a metal extractor from Freestyle was sort of similar to the lick method.
I would take an old library card or something similar -- a little pocket calendar card is usually about right -- but an expired credit card is sometimes too thick. I cut a strip about 3/8" wide off the card.
I take some scotch tape and cut off a strip to lay on top of the strip, and then use more tape to secure this piece of tape to the strip -- a small piece to the top of the strip, and a small piece to the bottom of the strip. Double-sided tape will work too. Just lay a piece down on the card strip -- about an inch and a half long piece.
I listen to the click also. When I hear the click, I insert the tape covered strip and push it in. You can feel the resistance after it gets pushed in a little ways. Then I slowly draw it out. More often than not, it will drag out the film leader with it.
