What is Smash Factor?

What is Smash Factor?
Smash Factor is a TrackMan data point that is the ratio of measured Ball Speed and measured Club Speed. You could think of it as a transfer of energy between the club and the ball.
The higher the smash factor, the higher the transfer of energy.
WHAT AFFECTS SMASH FACTOR?
There are three main factors that affect the Smash Factor:
Contact Point: Impact Location on Club Face
Spin Loft: TrackMan Data Point (Explained Below)
Face-to-Path: Club Face Relative to Path (Can be Open, Square or Closed)
WHAT IS SPIN LOFT?
Spin loft is the angle between Attack Angle and Dynamic Loft. We won’t get too deep in the weeds on Spin Loft in this article, but just know that it directly affects Ball Speed. We will talk more about Spin Loft in another blog.
WHAT SHOULD YOUR SMASH FACTOR BE?
A club is limited by its Coefficient of Restitution (COR), also known as the Trampoline Effect. Thanks to its Trampoline Effect, a driver provides the potential for the Ball Speed to be 1.5 times faster than the Club Speed. This number (1.5) is the club’s maximum Smash Factor.
For example, if a golfer’s Club Speed is 100 MPH, and their Ball Speed is 150 MPH, their Smash Factor is 1.50 (maximum transfer of energy).
A golfer that has a Club Speed of 100 MPH and a Ball Speed of 140 MPH has a Smash Factor of 1.40. Even though their speed is as fast as the previous golfer, the transfer of energy between the club and ball is lower, and as a result, Carry and Total Distance will be shorter.
SHOULD SMASH FACTOR BE THE SAME FOR ALL CLUBS?
No. In fact, here are the PGA Tour Averages for Smash Factor:
Driver: 1.48 | 3-Wood: 1.48 | 5-Wood: 1.47 | Hybrid: 1.46 | 3 Iron: 1.45 | 4 Iron: 1.43
5 Iron: 1.41 | 6 Iron: 1.38 | 7 Iron: 1.33 | 8 Iron: 1.32 | 9 Iron: 1.28 | PW: 1.23
INCREASING YOUR SMASH FACTOR & DISTANCE
In the two examples above, the Club Speed is exactly the same — 87 MPH. However, the Smash Factor in the first example is 1.40, and in the second, where the contact was high and on the toe, it is 1.29. The 0.11 difference in Smash Factors results in a 17.6 yard difference in Carry Distance.
