Source 1: PING Proving Grounds Data

PING Ball Speed: 167 mph (244.9 ft/s) - Source

Launch Angle 2000 RPM 2500 RPM 3000 RPM
7.5°273 yds275 yds278 yds
10°274 yds275 yds280 yds
12.5°275 yds279 yds284 yds
15°275 yds281 yds287 yds
17.5°275 yds283 yds289 yds

Key finding: Optimal carry at 17° launch with 2000-2500 RPM spin

Source 2: Ball Speed to Carry Distance

Pitchmarks Optimal launch conditions assumed (10-14° launch, appropriate spin) - Source

Source 3: Attack Angle Impact (160 mph ball speed)

PING Shows how launch angle and spin affect distance - Source

Attack Angle Launch Angle Spin Rate Carry Distance

+5°15.1°2179 RPM281 yards

17-yard improvement with positive angle of attack (higher launch, lower spin)

Analysis

Run the validation above to see the analysis of model accuracy.

Note: Published golf data may include factors beyond pure carry distance: Our model uses Cd=0.23 and Cl=1.5×S (spin ratio), tuned against published golf trajectory data.
