Well it is not factual or similar canopy/wingloading...
however after coming back from a boken humerous and working out with varying amounts of weight, I can tell you that it is between 13-14 lbs to "flare" a 120 Sabre2 loaded at 1.4 using a rope over a simple pulley from Home Depot with simple free weights hanging off. We thought it would be about 12 lbs, so once I could pull that down I tried one jump and my injured arm could not pull through the transition between pulling and pushing (about 25 degrees above and below the 90 degree point at the elbow). To practice flare, we made the contraption hanging from a chin-up bar, the small dumbell weights we already had, 1/4" rope, 2 pulleys and cut up the wooden handle rope that the therapist had gives to pull your bad arm up with the good arm for stretches (it is made to fit on the top of a door). She should know what I am talking about. It was a little squeky sometimes, but it worked.
The important thing is that if she jumps and realizes she cannot pull down with her bad arm, then she can:
1. try to flare both sides with one arm (tried it and didn't feel confident) or
2. flare as far as she can and PLF - but make certain not to flare further with the good arm than she can with the bad one obviously. It is actually hard to fight the urge for the good arm to flare because it was habit for me and it just wanted to pull the toggle all the way down.
Hope it helps. Good luck to her on returning in good health.
