how should I drop from the chair

[SuperioS]

Can someone tell me if I should just lower my body or just kick back the chair or something in between?

Slowly, lower yourself slowly, and check that the knot is in the correct position (behind the neck). If you jump or kick the chair, creating a kind of "bounce" when your weight falls, you run the risk of the knot changing position.

I will slowly bent my knees untill the rope takes my full weight and than kick the stool away so that I cannot step back.
I have tested it and know that it is not very painful. If you are more sensitive to pain the pain may stop you. In this case jumping would be more effective but probably more painful.
