I just read about FILD and based on the success rate am eager to try it. However, I tried practicing what I was going to do on my bed just and need to be clear about some things.

-Just how much do we move our fingers in the low movement phase? Do we press down very slightly on the bedsheet or do we just contract the finger muscle?

-I dont feel much when I just try contracting the finger muscle and when I try pushing slightly that finger or another nearby one twitches. Is that normal?

-This seems to work better when I try to only move the upper third of my index/middle finger. I that the right approach or do we try to move the whole finger?
