You are assuming a couple of things here Fore.
1) I have the ability to do something with that formula stuff.
2) I know the head angle.
I have an angle finder and a 3' level (to find a level piece of floor) but the graduations on the angle finder are so fine as to make its reading inaccurate at best. I would think that even a mildly incorrect head angle reading injected into your formula would produce a very inaccurate answer.
I do think and actual "on the floor" measurement would be the way to go. Thanks for your formula (or whatever that is!) anyway.
