How fast must one flap arms open palm downwards and side palm upwards motion in order to maintain loft? assume surface area of rest of arm is = up and down.

Not too fast. Just try it, go jump off a building and flap your arms as fast as possible. The higher the building, the better the results will be.

Y does this strange supposed woman follow me to every thread I make?

Women run from me.
Thus this person cannot possible be woman.
