Every serious golf brand talks about "performance." But what do the numbers actually mean — and more importantly, which numbers can your ball construction control?
Here's the factory guide to golf ball metrics.
Ball Speed — The Starting Point
Definition: The speed of the golf ball immediately after impact, measured in miles per hour (mph).
What it tells you: Ball speed is the primary input to distance. All else equal, more ball speed = more distance.
What affects it: The core is the biggest contributor to ball speed. Core material (polybutadiene rubber formulation), core size, and vulcanization process all affect how much energy the core stores and returns at impact. COR (Coefficient of Restitution) is the measurement — our 2-piece tour ball achieves COR 0.784.
Factory perspective: Ball speed differences between constructions are small but real. A 2-piece ball with a large, high-energy core typically produces slightly higher ball speeds than a 4-piece ball where the core is smaller (to make room for mantles). The trade-off: the 2-piece ball is faster, but the 4-piece ball has better spin control.
Smash Factor — The Efficiency Score
Definition: Ball speed divided by club speed. A measure of energy transfer efficiency.
Smash Factor = Ball Speed ÷ Club Speed
Example: If your club speed is 100 mph and ball speed is 148 mph, smash factor = 1.48.
What's a good smash factor?
- Driver: 1.45–1.50 (maximum legal limit: 1.50)
- 6-Iron: 1.35–1.40
- Wedge: 1.20–1.30
Higher smash factor = more efficient energy transfer = more distance for the same swing speed.
What affects it: Ball construction, clubhead design, and impact quality (center vs. off-center hit). A ball with a higher COR will produce a higher smash factor — but only if you hit the center of the clubface. No ball can fix a heel strike.
Factory perspective: We measure smash factor on every ball during testing. It's part of how we validate batch consistency. If three balls from the same batch produce smash factors of 1.47, 1.43, and 1.46 — that 0.04 spread tells us something about batch quality.
Launch Angle — The Trajectory Control
Definition: The angle at which the ball leaves the clubface relative to the ground, measured in degrees.
Typical launch angles:
- Driver: 10–16° (depending on swing speed and loft)
- 7-Iron: 16–22°
- Wedge: 25–35°
What affects it: Primarily the club (loft, attack angle). Secondarily the ball — dimple pattern and spin rate. A ball that spins more will launch slightly lower (spin creates lift, which changes the effective trajectory). A ball with a higher dimple count may launch slightly higher at the same spin rate.
Factory perspective: Launch angle is part of the trajectory system. You can't change it without also affecting spin, ball speed, and dimple aerodynamics. When we develop a ball, we're tuning the whole system, not optimizing one number in isolation.
Carry Distance — How Far the Ball Flies
Definition: The distance the ball travels through the air before first landing, measured in yards.
What affects it: Ball speed + launch angle + spin rate + dimple aerodynamics. All working together.
Carry is the most important distance metric for most golfers:
- Fairway bunkers, water hazards, and forced carries are all about carry, not total distance.
- Modern golf balls optimize carry over total because carry is predictable; roll is not.
Total Distance — Carry Plus Roll
Definition: Carry distance plus how far the ball rolls after landing.
What affects roll: Landing angle (steeper = less roll, flatter = more roll), ground conditions (soft fairway = less roll, firm links = more roll), and spin (more spin = steeper descent = less roll).
Factory perspective: "Longest ball" claims in marketing usually refer to total distance under optimized test conditions — hard fairways, optimized launch, robot testing. Real-world distance varies dramatically by player and conditions. We provide test data. We don't sell "30 yards longer" claims.
Peak Height and Descent Angle
Peak Height: How high the ball gets at the top of its trajectory. Affected by launch angle and spin. Higher isn't always better — too high costs distance in the wind.
Descent Angle: The angle at which the ball comes down to land. Steeper = less roll, more stopping power. Shallower = more roll. Wedge shots want a steep descent (~45–50°). Driver wants a shallower descent for roll-out.
Dispersion — The Consistency Metric
Definition: How much shot-to-shot variation exists in the same ball, same club, same player. Measured as left-right and long-short spread in yards.
This is arguably the most important number for brand owners that nobody markets. A ball that flies 280 yards on its best shot and 255 on its worst isn't a "280-yard ball." It's an inconsistent ball.
Our internal testing tracks shot dispersion as closely as we track distance. A ball that's 5 yards longer but 8 yards wider isn't an improvement.
How to Use Launch Monitor Data When Choosing a Ball for Your Brand
When you're evaluating balls for your brand:
- Don't look at one number in isolation. Ball speed without spin is meaningless. Carry without dispersion is incomplete.
- Test across multiple clubs. A ball that looks great with a 7-iron might spin too much with a driver.
- Test with real golfers, not just robots. Robot testing removes human variation — which is good for isolating ball differences, but bad for predicting how it feels to a real player.
- Compare same-condition data. "Our ball vs. Pro V1 on the same TrackMan, same day, same player" is valid. "Our ball tested on a TrackMan vs. Pro V1 data from a magazine tested on a different monitor last year" is not.
