I don't know any of that stuff. I ahven't gotten into that since back in the day. I know my bow was at 65 LBS, draw weight, and 29 inches of draw, and my arrows are 2314's or 2413's. Cant remeber now, lol. Guess I should know this, but Don't.
I just tried looking this up on wikipedia... :d Dudes, I failed Algaebra. Unless I am dealing with ingredients in cooking. Math is not my deal, well, not when they start throwing in letters anyway. I can do simple math in my head. But, letters do not belong in math! That is why they have English classes, and Math classes. Why make things complicated??? You guys don't want to hear my theory on weights and measurements. I made my instructor in cooks school hate me. lol.
