Tfox - you've already pointed out why you're getting different "real world" results than the ballistics calculation: Your bow is pointed "up" when it goes off. You're talking about a 3 yard misjudge with human error...and acting lke it's some kind of smoking gun that your slower arrow only drops and extra 1/2"over 3 yards at 40 yards...Think about whatyou're telling me...if 20 fps makes1/2" of difference over 3 yards, using the 40 YARD PIN. Try it with the 20 yard mark... See if it's still 1/2". HINT: It won't be.

Math doesn't lie. You can sit here and swear on your mother's grave that your arrow only drops 1" between 20 and 30 - no skin off my back bro. But I've shot enough to know that these calculations are fairly accurate - but you have to understand what the numbers are actually saying, and how that relates to the real world- and then how to manipulate the results.

Boy, you and Smartie Artie sure do get jacked up over a little physics. Like I told him- instead of complaining that it's wrong - get out your calculator and show me where I'm wrong.
