Hello miko0618,
Not sure why you'd want to know that as there's too many variables if you're looking for a formula or approx. height a bag is going to be thrown. Size/weight of bag, type of throw line and friction the bag endures as it's propelled upward along with the angle play a factor as the height it will obtain.
I'm very good at using a throw bag just by tossing without a BS, but looking at heights from 55' and less. If you want me to put an ascending line or pull line(after the throw-line) to heights like that, give me anywhere from 5 minutes to 13 minutes and I can put it wherever you want. 10 days ago I put my throw line in a crotch 2 1/2" wide at 45' on my 3rd try.
I'm saying this to not brag, as if people really care, but to show you heights in this category are obtainable without a big shot.
Take care.
