Two figures print beside every reading: the date, and how much of it was checked against documents.
Ask people how much faster they have become and the answer comes back generous by thirty-nine points. That is the measured gap in the randomized developer trial, set out in full with its design and its dates. It is why nothing here scores on how the year felt.
The same disagreement runs through whole economies. Three official surveys of the United States report AI adoption at 18 percent, 41 percent and 78 percent. They are not in conflict. They count different things. The 18 counts firms, from the U.S. Census Bureau’s business survey for November 2025 to January 2026. The 41 counts workers. The 78 counts the labor force at firms that have already adopted. A Federal Reserve staff note of 3 April 2026 sets the three side by side. It gives five reasons they diverge, one of which is the pressure senior leaders feel to report usage. Take a number like that into a board pack with its unit of measurement attached, or leave it out.
The checked figure is the one you can take into a meeting. A reading built on records will hold up when people disagree with it. A reading built on how the year felt will not.
What a checked reading buys is a price on your next move. On the worked reading below, twelve points of Direction are worth 3.6 points of Index. That is 2.4 at Direction’s own weight, and another 1.2 released from under the ceiling. It is what turns a number into an argument for spending: not what you are, but what one area is worth if you move it.
What to do. Take the reading twice. Once quickly, from memory, and once with the documents open beside you.
Who: you both times. How long: twenty minutes, then an afternoon. You end up with: two numbers and the distance between them. That distance is the most useful thing you will learn this quarter.
Three limits, stated once. The reading does not say whether your organization is safe. It does not forecast anything. And it cannot see whether the hours the machines handed back went to harder questions or to nothing much. That is why what you set out to do carries as much weight as anything else in the table.
