perfect reterning boomerang V2

I tried many types of boomerangs until I reached the best result, a boomerang that returns to the spot.
I tested methods and techniques on how best and most appropriate to throw the boomerang, and I found that it is best to throw the boomerang straight and strong, preferably on a day without much wind, if there is wind, throw the boomerang 45 degrees to the right.
If you appreciate and want to support me, please give a boost!
