Overdose TV glitch

Yay the first glitch I actually found, I did it a lot of time but it don't always works and it's easier to do it as a Zombie than human.

Where? Like the title says, in overdose map with the game style: Quarantine

small off-topic: some people said that it don,t give a lot of exp but if your pro enough and always survive as human then you will win a lot of exp.

STEP 1
Go to the operation room, hospital, where there's cameras.

STEP 2
Go, always in that room, in the room right beside facing the TV on top.

STEP 3
Try aiming at the crosshair like the picture on top (step 2), if it doesn't work then try aiming lower or higher, as I maybe not said, I did it a lot times but wasn't always working.

STEP 4
Sprint and run like if you wanted to hook to the TV. Like I said, with Zombie there's better chance to get there.

STEP 5
If you hook at the perfect, correct place, you should be able to move freely on the *opposite of floor (don't know the word in english)* but dont crouch. You can't jump at this step and in step 4 neither.

MISC PROBLEMS/QUESTION/WARNINGS
--If you're a human and you're hooked, then a zombie infect you (which is quite easy), you'll fall down

--If you try doing it too much and keep doing it but it don't work, you might be infected before you have time to do it (you can do it as zombie anyway)

--The timing of your jump, the speed you have, the place you hook can make you hook higher or even lower. Yup some screenies:

--It's high, it makes you looks like you fly and it looks like your mass jumping in a small area, BUT you're not invulnerable, it's even the opposite, your vulnerable but less than when you're on the ground (zombies just jump attack and bam your their BRO)
