Howdy, AW --
JG weighing in again. Been away a while -- work & kid, don't you know. ; )
I know other people have said this, but I just wanted to say that I think that you should start VERY simply and work your way up.
Remember that according to the rules of the Challenge, you have to bear ALL of the costs of your demonstration. If you have to find "broken" people, then get them all into a controlled environment to heal them, YOU will be paying for their transportation and lodging. If a doctor will be required to look the people over before & after your demonstration (which is likely), YOU will have to pay for the doctor's time. And so forth. That's going to get expensive.
And simple. We're also looking for simple. Because what we want to do is demonstrate that you are doing something that can't be explained by ANYthing else. We want a test so obvious, so cut & dry, that there can be absolutely NO doubting that you're achieving the effect paranormally. No placebo effect or confirmation bias. Something like broken bones. Can you heal, by touch, a broken bone? Remember, you are going to have to pay for the time and transportation of any test subject(s) in question, the time of the doctor(s), and for x-rays.
If you still want to pursue healing, then by all means do so -- but do come up with a list of things that you can heal. We'll try to figure out which ones would be the simplest -- and least expensive.
BUT -- if you can do more than one thing, then try picking something that is cheaper to test. For example, you mention that you can control the wind:
Since you say "not only", this implies that you can cause the air in a room to flow in a chosen direction. Is that correct? At what rate can you make the air move? Could you knock over an object across the room? How light does the object have to be? Could you, say, knock over an empty 2 liter soda bottle?
How precise can you move the airflow? If I were to set up, say, three soda bottles, could you knock over just one of them?
See where I'm going with this? The test would consist of you, possibly a friend, and some empty 2 liter soda bottles. The only thing you'd have to pay for is transportation & lodging of you and your buddy (and possibly some soda bottles) to/at the test site. If there's a proctor in your area, there'd be practically no cost at all. AND it would give you the "drop dead" evidence we all want.
