3 Common Golf Stats Myths that HURT your scores w/ Mark Broadie

We sit down with the creator of the Strokes Gained concept, Mark Broadie to talk about golf stats myths and how a lot of our common conceptions of golf stats like FIR and GIR aren’t helping us make smart decisions.


The Problem with Traditional Golf Stats

I think that’s a big myth that you can learn much at all from traditional stats.

Mark contends that traditional stats are both uninformative and sometimes completely misleading.  For instance,  if you take a look at Tiger Woods in his heyday, the traditional stats really give no clue to why he was so dominate. His number of fairways hit wasn’t a good measure, greens in regulation wasn’t such a great measure, and putts per round wasn’t such a good measure… He didn’t look like he was one of the best golfers ever by their traditional stats.

The main flaw in traditional stats is you measure things in terms of strokes (in other words a yes or no answer).  In that paradigm how do you compare hitting a drive 300 yards versus 250 yards that both end up in the fairway?

We know a 300 yard drive in the fairway is generally better than a 250 yard drive, but how much? It’s very hard to quantify driving distance and compare that to driving accuracy, to compare that with proximity to the hole, to compare that with how many putts did you take?

The first flaw is that the units of traditional stats are not consistent with each other so it makes them hard to compare. Strokes gained measures everything in terms of stroke. You can measure driving with putting and it’s all in consistent units.

Another flaw of traditional stats is that they’re sort of zero, one. You either hit a fairway or you didn’t.

Another flaw of traditional stats is that they’re sort of zero, one. You either hit a fairway or you didn’t. It doesn’t distinguish between missing a fairway in the first cut of rough or missing it in the woods or missing it in the water or missing it out of bounds.

If you want to learn more about Strokes Gained here’s a great article on the concept.

If you’re looking for a way to track strokes gained check out the app Mark mentioned in the podcast GolfMetrics. The Golfmetrics app allows you to enter information and see strokes gained results with any Apple or Android smart phone. (Of course the app provides traditional stats as well.) No longer do you have to rely on your memory, inaccurate traditional stats, or guesswork. Now you can better focus your limited practice time and track your improvement.

YEARS OF RESEARCH AND DESIGN IN THE MAKING; THE EDEL SINGLE LENGTH SYSTEM SLS-01 IRONS ARE NOW HERE. SIMPLIFY YOUR GAME.

Traditional logic enforces the notion that variable length irons are correct and that smart people before us deciphered the most accurate way to play the game. Yet, few have questioned the reason why our clubs variate in length.

Ockham’s Razor is a scientific technique or discovery tool to guide researchers and scientists which states Among competing hypotheses, the one with the fewest assumptions should be selected. In golf terms, a set of clubs that allows the player to maintain a single ball position, swing plane, and rhythm rate would provide the logical explanation to achieve optimal performance.

All with a club that has singularity of length, weight, bounce, shaft weight, and shaft flex to optimize the simplicity of repeating your ideal swing.

SIMPLIFY YOUR GAME. SINGLE LENGTH. SINGLE SWING.
