here are some clicking methods that you might know of and HOW to do them.

1. Normal click.
you just click as usual. :)

2. butterfly
how to do:
put your index finger and your middle finger on one MB. and then you start to rapidly click with one finger and another, which got me 15 cps. a big mouse is recommended for this to work.

3, jitter click

how it works: when you give your arm a strong, tight-feeling power, your hand vibrates and starts click in insane speeds. i never found this clicking method helpful.

how to do: get your finger on top of your mouse, and give your arm some power and pressure and make it vibrate. practice on and on.

4. double/triple/quadruple click

how it works: i have no idea but one click makes 2/3/4 clicks.

how to do: i usually move my hand further than usual and click lightly. i get 2 clicks in 1. (i cant do 3,4)

5. DRAG CLICK!!!!!!

how it works: when your hand and mouse has lots of friction and you lightly press on it (dont press on it) and slide it down, it will vibrate causing INSANEEEE CLICKING.

how to know it works: try double clicking. if it works your good.
if your mouse is bumpy or matte or something, good. the more matte it is, the better.

I FOUND THIS YT VID HELPFUL: https://www.youtube.com/watch?v=XqRCMd_18S8
on the practice part, follow the things he does.

when you think you got it, here is how to know if ur almost there.
put your hand high up like the tutorial, and slide it down, a bit of pressure.
when your finger is wriggling because of the friction, YOUR SO GOOD AT THIS.
if you here some type of rough wiping noise thats the same too
now when that happens, try putting a bit more pressure and you'll hear this: CLICKICLICKLCIKCLCIKCLCICKCLICCICL
GOOD YOU DRAg CLICKED
