One possibility I have yet to try but was 'revealed' to me by Dean Osmer, a local seattle fabricator, is to twist the bar first then have it rolled. The result is a helix. You may still need to tweak, but the hard part of the twist is in there.
What would a formula look like for the above? I'm guessing if the helix makes it one time around in ten feet then one twist might be a place to start(within the length of that 10' rise). With my luck, I'd wind up with a pile of scrap getting it right. 
my 2 cents

The rail for a curved stairway has a twist in it as wellas a curve.
Do any of you have any good ideas for doing this twist?
I've done several of these, the curve is easy, make a pattern from the stairs or lay out the curve on the shop floor and bend the iron to it.
The twisting is where I always have trouble.  I go to war w/ big wrenches etc. and fight for hours to get it right.
