Guides
Straight answers to the questions people ask about their launch monitor numbers. Every figure on these pages comes from a published source or from the app's own code, and each guide lists its sources at the bottom.
- How accurate is the Rapsodo MLM2PRO?
What the MLM2PRO measures, what it calculates, what it cannot see at all, and which of its numbers you can build practice on.
- Is launch-monitor spin accurate?
Why spin rate is the least trustworthy number on a consumer launch monitor, what the peer-reviewed agreement data says, and what to do with it instead.
- Smash factor by club: what good looks like
Tour smash factor for every club from driver to wedge, why it falls with loft, what moves yours, and how many shots before your average means anything.
- Driver attack angle: why the tour average isn't your target
The PGA Tour hits slightly down on the driver. Why that is not what you should copy, why yards-per-degree charts mislead, and how far to trust your launch monitor on it.
- Range balls vs premium balls: what changes in your numbers
What a swing robot found when it hit range balls and premium balls: distance, dispersion and spin, what mats add on top, and how to compare sessions honestly.
- How many shots before a launch-monitor average means anything?
How many shots per club before an average, a change or a dispersion figure is worth reading, and how big a change has to be before it is real.
- How to build a gapping chart from launch monitor data
A step-by-step method for an honest yardage book from your launch monitor: one ball and surface, enough shots per club, averages with ranges, and gaps that are real.
