Spine Chart Confusion

[Beendare]

In theory, theory and reality match. In practice, reality seldom follows theory.

My current set up likes being a little stiffer than what the charts say, but I've also found the three rivers calculator to be pretty darn accurate.

I'm not saying the Stu Miller or 3 Rivers calculators are perfect...but it gets me to within about 25g of tip weight or 1/2" of arrow.

Thats pretty darn close.
