Top 5 reasons why full suspension fails?

[mini_weeny]

Other than bad knots and bad anchor point are there any other reasons for full suspension failure?what is the success rate?

 

[Ramirez]

Dont know about success rate. But the only other I can think of is being discovered too early.

Being discovered.
Hanging point breaking.
Hanging point dropping down. (I used a pull up bar, didn't drop but could have.)
Rope breaking.
Rope untying by itself. (Happened twice or thrice to me.)
Not being able to kick the chair. (This is why I'm writing this today instead of being in a better place.)
And one time I did manage to kick down the chair but I should have been one centimeter higher.
Not enough vertical space. (I'd tie the rope, drop down to a pillow because it was easier than kicking the chair, drop down to floor, and realize my toes could still touch the floor although very barely. I was only 99% in full suspension. Kinda not that bad, but not the most pleasant feeling ever being there tiptoed, but in some way it was cool and exciting and I literally wanted to experience it again immediately afterwards. I felt more alive than in ages and it felt like I was an adventurer.
Managing to climb back up (Happened after the tip-toing, I managed to pull the fallen chair closer with my leg and stand on it and untie myself.)

I guess the only other way it could fail was if you somehow didn't fall unconscious and die, but in that case, it would end up with either being discovered or managing to climb back up and untying yourself. Unless you didn't manage either and died of thirst and starvation hanging there for days (or maybe the body would eventually break after hanging there for hours/days) but that is very unlikely.

Good rope, good knot in a good place (on the neck), good hanging point, no one to discover you for at least 30 minutes preferably an hour, enough vertical space so you will hang and toes won't be able to touch anything, and enough bravery to do it, and I'd say there's a 99% chance you'll get to know what happens after ctb. Unless you have scissors in your hand and manage to cut the rope or untie the rope but that's very unlikely and hard.
