The Recreational Golfer

Assessing Golfer Performance Using Golfmetrics via Game Golf, SkyCaddie, etc.

Recommended Posts

The abstract below is for a nine-page paper found at
http://www.columbia.edu/~mnb2/broadi...g_v_200804.pdf


The software application Golfmetrics was created to capture and store golfer shot data and to quantify differences in shot patterns between players of different skill levels. Across golfers it is shown, somewhat surprisingly, that longer hitters tend to be straighter than shorter hitters. Individual golfers can be measured relative to a benchmark to assess relative accuracy and to suggest whether to focus on increasing distance or decreasing directional errors. For amateur golfers, distance errors on short game and sand shots are shown to be about three times larger than direction errors. Shot value is a quantitative measure of the quality of each shot in comparison to a scratch golfer. Shot value analysis is a useful way to measure consistency, assess a golfer’s relative strengths and weaknesses, and to indicate where practice and improvement are most needed. For amateur golfers a significant contributor to high scores is inconsistency, i.e., a relatively small number of awful shots. This research also quantifies the contributions of each part of the golf game (putting, short game, sand game or long game) to overall scores for golfers of different abilities. The long game is found to be the biggest factor in the difference in scores between pros and amateurs and between low- and high-handicap amateurs.

I'm reading Broadie's book right now, and I thought to myself "why isn't Golfmetrics an App on the App Store(s)"?

Turns out it kinda might be, if ShowMe is at all related as it seems to be. But also because the platform probably isn't exactly ripe: you'd have to enter in a LOT of data (precise location data for EVERY shot, in EVERY round, etc.) and that might only appeal to 10k users or so.

I'm reading the book as well and was thinking the same. Strokes Gained stats tied into the ShowMe or the Game Golf product would be amazing.

The only major editing I can see offhand would be identifying the pin location for each hole. I would gladly take the 10-15 mins to do it if I had a breakdown every round of my strokes gained, with an option to view my results alongside a chart of PGA/Scratch/80/90 numbers.

You shouldn't have to physically locate the pin. Why doesn't Game Golf assign one of the tags as the pin and when you get to the flag just tag that pin tag. The software can then be supported to locate that as the flag location. Also game  golf needs to let you locate your putts.

    • I'll do that with friends.  One time I was hitting well at an indoor range.  So I'd just hit the same spot on the wall as my friend did.  He noticed pretty quickly actually.  It's a good drill (break the glass type thing)
    • They have moved the 3-point line back. Baseball has allowed the ball to be juiced to increase home-run rates. https://fivethirtyeight.com/features/in-mlbs-new-home-run-era-its-the-baseballs-that-are-juicing/ No one was complaining about all the HR's in baseball until they found out that the players were taking steroids. They found it exciting, and baseball was at its peak popularity. https://www.beyondtheboxscore.com/2014/2/10/5390172/major-league-attendance-trends-1950-2013 There has been a down turn since the implementation of more PED restrictions. The primary issue is, if PGA Tour players think that playing with those clubs the day before the tournament starts will screw up their game, then there is no way this gets implemented.  
    • It really depends upon why they're a 15 handicap. A high swing speed is basically all you need to back up the ball. If they can make a 56 degree wedge hiss aggressively, they can probably back it up on firm greens. There are many 15 handicaps who can swing really fast, but hit lots of trees on the way to the green.   Sure, this is true. Even instructors who've been "doing it for years" and "seen 100,000s of thousands of golfers" can make be mistaken about someone's ability even seeing them up close. The problem is no one knows what's going on "in your swing" except yourself. Even then, may of us don't know. The 300 yard 20 capper example you gave is not unrealistic. An old instructor who fit many clubs over half a century told me that the average male should be able to get 105mph swing speed. He based this on understanding mechanics and seeing people's swings are not even close to optimal. He's a TGM advocate, and seems to know his stuff. On the internet could sound just like a 76 year old kooky golfer, but in real life he makes a lot of sense and has a great swing to back it.
    • I'm not very good. With that being said, my yardage gaps are consistent (10-15yds) all the way through my bag so fairway shots >95 yards are always full shots for me. I practice <95yd shots on the range regularly, so I am capable of rolling a 3/4 swing out across my bag. Now, I'm not very good (remember?). With that being said, I am in trouble frequently off the tee and I have to focus on less-than-full swings regularly to get the ball back in play. Off-fairway/slight trouble, my go-to play is a 6i since i can keep it low (read: under a tree) and can control distance "pretty well" anywhere from 100-150yds, typically staying within 20 yards of intended target. Sometimes this is more of a punch shot, other times I am trying to draw it around trees (mostly unsuccessfully). But - If I am my full 6i distance though, I am hitting a full 6. The biggest problem I have is instead of taking a 3/4 full swing, I have the tendency to decelerate leading me to hit about 24" behind the ball - this is why I typically opt in for full swings when I can. Purely Mental... Maybe I'll get on the range and try this "flighting" technique a bit more
