Open the Records tab and scroll to the ladder: one bar per club, longest carry at the top, your best-ever number printed at the end of every bar. It is the most satisfying plate on the board and the easiest one to misread.
Here is the misreading, and it is expensive. You look at the 7-iron row, see 174 yards of carry, and file it away as "my 7-iron." Saturday you have 174 to a front pin with a bunker guarding it, you pull the 7, and you find the bunker. Nothing was wrong with the sim, the ball, or the swing. You clubbed off the wrong number.
One shot is not a population
Every bar on that ladder is a single swing — the longest carry that loft has ever produced in one of our bays. Out of the four hundred 7-irons you have hit here, that is the one: one day, one lie, your hands in exactly the right place.
A yardage is a different animal. Your capability number for a club is the median of your twenty best-struck shots with it, and "best-struck" means ranked by contact quality — smash factor, or ball speed within that one club when no marker was on it — never ranked by distance. That ranking rule is not fussiness. Rank twenty shots by distance and you have selected the twenty biggest flukes: the flyers, the jacked-up ones, the one that caught a gust of the sim gods. Our house rule is blunt about the cost — distance-ranking overstates your gapping by half a club or more.
Shot Scope, working from more than 160 million tracked shots, arrives at the same rule from the other direction. Their Performance Average "removes all the outliers (good and bad) to give a yardage based on the distance a well struck golf shot will travel. This is the number you should refer to when selecting a club for an approach shot."
One club, two honest numbers, two different populations. The record is your peak. The yardage is your plateau.
What the mix-up costs
The cost is always in the same direction: short.
Shot Scope's figures for the share of shots amateurs leave short of the green run 37.6% at scratch, 45.7% at 10, 55.5% at 15, 62.5% at 20, and 69.7% at 25. Their own diagnosis: "ultimately it comes down to club choice and strike."
Club choice. That is this exact error, played out a hundred million times. Every golfer who has ever quoted their longest 7-iron as their 7-iron number is standing in the front bunker blaming the strike, and about half the time it was the number.
One thing the ladder does get right, on every row: it is carry — flight only, where the ball came down, before it did anything on the ground. That is the correct basis for an approach club, and it is labeled on the plate rather than left for you to assume, because a yardage that quietly means something other than what you thought is worse than no yardage at all.
So why show it at all?
Because a ladder of bests still shows the shape of your bag, and shape survives the population problem.
Look at the steps between adjacent bars. If your best 4-hybrid carry and your best 5-iron carry sit four yards apart, you own two clubs doing one job — and those two rows are the best case for both of them. If a step is enormous, twenty-five or thirty yards, there is a shot on the golf course you cannot hit and have been fudging with a half swing.
For calibration, TrackMan's 2023 PGA Tour average carries step the irons like a staircase: 3-iron 218, then 209, 199, 188, 176, 164, 152, and a pitching wedge at 142 — nine to twelve yards a rung, all the way down. Those are averages, not records, which is exactly why they are worth quoting. Our own target is roughly ten to fifteen yards between adjacent clubs, with no holes and no stacked overlaps.
Then look at the top of that same chart: 3-wood 249 carry, 5-wood 236, hybrid 231, 3-iron 218. Five yards between the 5-wood and the hybrid. Even at the top of the game the long end bunches up, so if yours does you are in decent company — and you still only get fourteen slots.
A record ladder can raise all of this. It cannot settle any of it. Nobody should bend a loft off it.
The rows that aren't in your bag
One more thing makes this a bad gapping chart, and it is deliberate. The ladder is per-loft and any club: it shows the best you have ever hit a 7-iron, whoever's 7-iron it was. The demo you took for six swings, the club you borrowed and gave back — if it produced your best carry at that loft, it owns that row.
That is right for a personal record. "The best I've ever hit a 7-iron" does not care whose 7-iron it was, and hiding a great strike because you handed the club back would understate what you can actually do.
It is wrong for gapping, because you gap the bag you carry. A row belonging to a club you do not own is a fact about you, not a slot in your set — and a six-swing demo record is a best-of-six, which is thinner than thin. Read it as interesting, never as a purchase order. If a club you tried once sits above one you own, that is a conversation worth having after you have measured both properly.
Where your real number lives
Your yardage is built from twenty clean strikes. Below twenty we show you a count — 14/20 — and no yardage at all, because a made-up number you believe is worse than an honest one you are still earning.
Earning them takes about an hour. Bring the full set to a bay and hit each club with your Saturday swing rather than your launch-monitor swing; gapping your bag on a launch monitor is the whole protocol. Every shot stays on that club's detail page afterward, mishits included — the misses are the diagnosis, and they are never averaged into the yardage.
After that, read the two plates for what each is actually good at. The ladder tells you the shape of your bag and the ceiling of your golf. Gapping tells you what to pull. The 174 is genuinely yours. It just isn't your 7-iron.

Golf Balls: What You Should Actually Play
You can spend $600 on a new driver and gain four yards. Or you can spend $35 on the right dozen golf balls and change how every single shot behaves — off the tee, into the green, and on those little pitches that decide whether you make bogey or double. The ball is the only piece of equipment you use on literally every stroke, and it's the cheapest thing in your bag to get right. Most golfers never think about it. Here's what's actually going on inside that little sphere, and what you should really be playing.
