The chart is to convert the arrow deflection to pounds of spine weight.

A spine tester shows how much deflection(bend) an arrow has with a 2# weight hung from it. That deflection coincides with with a spine weight on the chart. example, .578" deflection means the arrow is spined for45#, .473" for 55# spine, .400" for 65# spine, etc
