you are actuallyclaiming that a bow will shoot 2 arrows of different weights with the same ke and efficiency.
I am simply telling you exactly what the chronograph reads.
Spine issues will most likely give you false findings,spine must be on for an arrow to absorbthe maximum amount of energy to give you accurate findings.
No, it's not perfect but by doing thisthere should beeither adrastic increase or decrease in KE. If what Sylvan says is true then the KE from an arrow weighing a few thousand grains should be off the charts.
I don't have the time, energy, or money to make this perfect. If someone else has the time and moneyto conduct an absolute perfectly controled test then please do.
In the typical bow force graph below (used from huntersfriend.com)the draw force curve on the left is the bows input energy, or the ammount of energy it takesa person to pull the bow to full draw.On the right is the bows output energy. A bow only stores a specific amount of energy. Sets say that the shooter puts 100 pounds of energy into getting the bow to full draw. That represents the area under the blue line on the left.The bow will store that energy but the output energy will be less due to friction. Representedby the area under the red line.For arguments sake lets say the out put energy is 95 pounds (5% lost to friction).
To use an extreme example if an arrow weighed exactly the same as the amount of energy that the bow was capable of applying tothatarrow then the bow would not be able to accelerate that arrow and the arrow would have zero KE.
This example is obviously way on the side of diminished returns but it illustrates the point perfectly.
