Use this table to compare weight classes quickly, then verify the best balance point with FOC and broadhead grouping checks.
FOC Guide
Rising arrow weight may improve momentum while reducing speed. Keep FOC within your target range so heavier builds still launch cleanly.

FAQ
Does heavier arrow weight always raise kinetic energy?
Not always. KE depends on both mass and speed, so very large speed losses can offset mass gains.
How should I use this output?
Use it for directional comparisons, then confirm speed and impact behavior with real equipment testing.
Should I prioritize KE, momentum, or FOC?
Use all three together to balance efficiency, penetration context, and flight stability.
