Well, I looked over some of it....and it's way over my head. But one thing I just don't understand......how can you have the mass of an arrow and then REMAINING mass....virtual mass. My logical and not mathematical brain tells me that's a made up number. Remaining mass of what?
And my 400 gr arrow is flying 290. Although I haven't chrono'd a 550 gr arrow. Thanks for the explanation. This is actually kinda fun for me.
