Preparing for partial hanging

[BlessedBeTheFlame]

I decided to do partial hanging as my main method and have some questions. My big worry is surviving as a vegetable frankly. I'm taking myself out of this world for being worthless and don't wanna close that off entirely.
The exact plan is this: I have a PPE rope and will tie a strong knot on one end. I will then pull it through the upper slit of a door until the knot keeps it in place. I will tie a belt around my neck and the rope securely around the belt. Thereby I will be strangled by the belt, which will be constricted by the rope. I have a number of questions about this plan:
1.) What weight does the rope need to hold? I bought the strongest I could find, that could reasonable fit through the door slit. Does it need to hold 50% of your weight? 20%? Or even 100%?
2.) What knot is most preferable for this idea?
3.) Someone mentioned how the belt makes it way easier. What do I need to do for the belt to properly work?
4.) What could cause for this to stop working and for me to wake up midway? (which I obviously wanna mitigate)

To be on the safe side get a material that can hold atleast 2 or 3 times your weight. Pressure from conscious body weight is less than pressure from an unconscious body weight.

Slip knot for noose and snuggle hitch knot for your anchor point are the recommended ones

Failure chance could be:
The knot may slip and the rope could fall through the slit.
The point of connection b/n your belt and rope may break.

It's always better to only use one long enough material to reduce snapping of ligature.

Instead of holding the ligature through the slit with a knot, it's better to tie it on the door Knob and throw the rope end with the noose to the other side over the top and lock door.

For partial any knots work except hangman' s knot, u can find details in hanging megathread anyways. It won't work if u r doing it really slowly , only possible when ur emotions take over ur si. I would recommend long drop though ,its is always better and painless all u need is a god damn high spot to do it.
