How to Track Golf Equipment Changes with golfity

Most golfers buy a new club, hit it well for two range sessions, and decide it works. Three months later nobody can say whether it saved a single stroke. If you track golf equipment changes the same way you track your rounds, you get a real answer: how many strokes per round the new club gains or loses compared with the one it replaced.

golfity doesn’t have a separate equipment log. It doesn’t need one. Your per-club strokes gained is built from the club name on every shot you record, and that detail is what makes a clean before-and-after comparison possible.

How golfity Stores Your Club Data

Every shot you log in shot-by-shot mode saves the club you picked. When golfity builds your By Club table in the Strokes Gained stats, it groups your shots by that club name and reports three numbers for each one:

• # Shots: how many shots you have hit with it
• SG/Rnd: strokes gained per round with that club, against your chosen benchmark
• SG/Shot: strokes gained divided by the number of shots

That has two consequences for equipment tracking.

First, removing a club from your bag doesn’t erase its history. The shots you hit with it are still in your rounds, so the club keeps appearing in the By Club table.

Second, if the new club goes into the bag under the same name as the old one, golfity has no way to tell them apart. Your new driver’s shots get blended into two seasons of old driver shots, and any difference disappears into the average.

Track Club Changes by Giving the New Club Its Own Name

The fix takes about 30 seconds. When a new club goes in the bag, open Profile → Settings → Your Clubs, remove the old one, and add the new club with a name you’ll recognize later. For example:

• Driver becomes Driver 2026
• 4 Iron becomes 4 Hybrid (a different club, so the name changes anyway)
• 56 becomes 56 Vokey if you’re swapping one sand wedge for another

Tap Save Changes. From your next round on, every shot with the new club builds its own row in the By Club table, and the old club’s row stays frozen with its complete history. You now have a baseline and a test group in the same view. (If you need the full walkthrough of the clubs screen, see setting up your clubs in golfity.)

Keep names short, since they appear in the club picker on every shot. If you log both clubs as Driver, the comparison is lost for good, so pick the new name before the first round.

Comparing Old and New: A Worked Example

Say you’re a 15 handicap comparing yourself to a 10-handicap benchmark. Your old driver has a long history:

The old driver cost you about 1.1 strokes per round against your benchmark. After roughly four or five rounds, the new one is costing 0.4. On paper, that’s seven tenths of a stroke per round from one club.

Before you give the new driver the credit, check the SG/Shot column. SG/Rnd depends on how often you hit the club, and if you started laying up with a 3 wood on tight holes during the same stretch, driver SG per round drops even if the club is identical. SG/Shot takes usage out of the picture. Here it moved from -0.09 to -0.03, which suggests the club itself is performing better and you aren’t just hitting it less.

Then check what happened around it. If your approach play also improved by half a stroke over the same rounds, the driver may be leaving you shorter approaches, which counts as real value. It can also mean you were playing well in general. One club comparison over five rounds won’t settle it on its own.

How Many Shots You Need Before Trusting the Numbers

Sample size decides how quickly you get an answer, and it varies a lot by club.

A driver gets 12 to 14 tee shots per round. After five rounds you have 60 to 70 shots, which is enough to see a meaningful shift. A 4 hybrid might get two shots a round. Five rounds gives you ten shots, and one topped hybrid can swing the SG/Shot number by several hundredths.

Rough guidelines:

• Driver, putter: 5 to 6 rounds before the numbers mean much
• Scoring wedges, mid irons: 8 to 10 rounds
• Long irons, hybrids, fairway woods: 12 or more rounds, often a full season

For the reasoning behind these numbers, see how many rounds you need for accurate golf stats. If you judge a new 4 hybrid after three rounds, you’re mostly measuring luck.

Use Stats Filters to Check the Trend

golfity Pro lets you filter your stats to your last 3, 5, or 10 rounds, or to the last 3, 6, or 12 months. The filters don’t work on specific dates, which is exactly why renaming the new club matters. Filters are still useful for two checks, though:

1. Is the new club stable? Compare its SG/Shot over the last 5 rounds against the last 10. If the recent number keeps getting better, you might still be adjusting to the club. If it’s flat, you probably have your answer.
2. Did anything else change? Look at your overall strokes gained by category over the same window. If every category improved, give the new club less of the credit.

Clubs Worth Tracking This Way

Any club swap is worth a rename, but these give the most useful answers:

• Driver. It’s the club you hit most often besides the putter, and it has the biggest retail price tag. It’s also where launch monitor numbers and on-course results disagree most. A driver that adds 8 yards on a simulator can still lose strokes on the course if it misses wider. Our post on launch monitor data vs on-course data covers that gap.
• Long iron replaced by a hybrid. This is the classic amateur swap, and the data usually settles it quickly once you have enough shots.
• Putter. Putting is measured with strokes gained putting, and you use the putter every hole, so a new putter builds a sample faster than any other club.
• Wedge setup. If you move from two wedges to three, give each new wedge a distinct name (50, 54, 58) so you can see which gap actually gets used and which loses strokes.

What the Data Won’t Tell You

Per-club strokes gained measures results, not causes. If Driver 2026 is gaining strokes, it could be the head, the shaft, the loft, or the lesson you took the same month. You can separate those only if you change one thing at a time, which most golfers don’t.

It also can’t judge a club you rarely pull out. If the data shows your 3 wood has 14 shots across a whole season, the more useful question is whether it belongs in the bag at all, not whether a new one would be better.

A Simple Routine for Every New Club

1. Before the first round, rename the club in Your Clubs so its history starts clean.
2. Track every round in shot-by-shot mode with club selection turned on.
3. Wait for enough shots for that club type before judging it.
4. Compare SG/Shot, not just SG/Rnd, between the old and new rows.
5. Look at your other categories over the same period to rule out a general hot streak.

A new club is a bet that it will make you better. Tracking it this way costs a few seconds, and it tells you whether the bet paid off or whether your old club was fine all along.
