Help Hanging jump backwards [weird question]

[abirbul60024]

usually when you hang yourself, you jump forwards from the chair, what if you jump backwards? does it affect anything?

Since you really want the rope to be behind your head so even pressure is applied, stepping off forward is easiest.
I would not actually jump. That will put a heavy load spike on the rope and tie-off point. No reason to invite a failure when you have gotten to that point in your plan.
Be focused on success. Ease off the chair.
