Hi,
I cant say i did have that problem.
I think why i did it right the first time was due to practice....in the pool. Is sat on the side of the pool like i sat in the door, focused "jumped" and went through the drill (while sinking to the bottom of the pool) i did this for about 40 times (people look kinda strange at ya....but anyway).
And did the exect same thing in the air !!
That won't solve the problem of being in the air....Or maybe it will !!
