It cannot EVER be proven unless you have ammo with an ES/SD of ZERO! Which is impossible. You can chart things out and see a possible "trend" but unless it's 100% reliable and CONSISTENT then the data is null and void. Lead sled, multiple chronys, remote trigger, etc is what's needed for the test to be even somewhat plausible in my eyes. I definitely love the spaceship comment...but don't tell NASA or they will spend a few billion bucks trying to figure out how to make the Earth lighter!
