Reverse Lookup (Arrow -> Bow)
Calculates required limb weight for these arrows at 28" draw.
User Manual
1. BASIC TAB
Use this for quick checks. Enter your bow specs and arrow details. The 'Live Diagnosis' bar shows if your arrow is Stiff (Left/Green-Yellow) or Weak (Right/Yellow-Red).
2. ADVANCED TAB
Includes FOC (Front of Center) calculations and allows custom GPI (Grains Per Inch) inputs. Use this if you are building custom arrows.
3. REVERSE LOOKUP
Enter a specific arrow setup to find out what Bow Weight (at 28") is required to shoot it perfectly.
INTERPRETING RESULTS
• Dynamic Load: The actual force acting on the arrow.
• Perfect Match: The arrow spine matches the bow's dynamic load.
• Stiff/Weak: The arrow bends too little or too much.
Archery Tuning Theory
1. DYNAMIC LOAD CALCULATION
The 'Dynamic Load' represents the effective force the arrow experiences upon release.
- Base Weight: Rated Weight + 2lbs for every inch of draw over 28".
- Arrow Length Factor: Adds ~5lbs of virtual load per inch over 28".
- Point Weight Factor: Adds ~3lbs of virtual load for every 25 grains over 100gr.
2. SPINE DEFLECTION
This app maps your calculated Dynamic Load to an ideal Static Deflection using a non-linear curve derived from empirical charts.
3. FOC (FRONT OF CENTER)
Ideal Range: 10-15% for target recurve.
