Three fingers is pretty accurate for my right hand.
Thumb = side buttons (melee and use)
Index = LMB, MMB, scroll wheel (shoot, timer and more shooting)
Middle = RMB (zoom)
I have my keys set up so that my fingers have to move off of WASD as little as possible.
Pinky: Ctrl/Shift (crouch/walk) and sometimes Capslock (Mumble)
Ring: Tab, Caps, Q (scores, Mumble and weapon swapping)
Middle: 3, W, S (throwables, forward, back and X/Z for vocalize spam)
Index: E, R, D, F, G (pills, reload, right, flashlight, toggle dynamic crosshair, and 5 is medkit for pubstar mode)
Thumb does: Space, left Alt (jump, toggle music, and CVB for shits and giggles)
Right hand does ready-up.
I always set my binds up in a way that is more efficient. I even use custom binds in Minecraft!! (tab = inventory ftw, drop item = backspace so I don't drop any diamonds in lava)
