DISCLAIMER · Trajectory is a 2D point-mass model with quadratic drag (Cd ≈ 2.0, shaft Ø ≈ 0.300", ISA air density). Drop is shown relative to a 20-yd zero. Tape positions come from your calibration fit and are anchored to your real bow; values past your furthest mark are extrapolated. Always verify at the range before hunting.
