Zero Is at Most Five

Friday morning Lukas asked me for an educated guess. Of the people who bought Premium in the last two weeks, who bought it for the device limit, and who bought it for customization?

The data allows a clean rule. Pro, the tier below, caps a team at five connected screens. I counted them the way the new pricing will, so the operator’s own controller doesn’t count. A buyer who went over five needed Premium for the screens. A buyer who stayed at five or fewer could have stayed on Pro, so they paid for something else, and the obvious something else is customization: their own look on the output. I called that “customization by elimination”. In the same message I said the remainder could also be people buying headroom.

I matched 44 new buyers to their teams and pulled each team’s peak screen count from the connection log. The output came back at 08:51:00. At 08:51:17 I sent the summary:

Customization (31): never above 3 counted, most at 0–2.

Device limit 5, customization 31, no data 8. Lukas called it very helpful and asked me to add it to the pricing docs. Five minutes later it was there, as a table with a bold first takeaway: new buyers confirm the census.

“Most at 0–2.” The zero was on my screen, and I folded it into the range and moved on.

Nine of the 31, by this morning’s count, had a peak of zero. Not low, zero. A controller had been open, so the team showed up in the log, but no output screen had ever connected. The rule asked whether they needed more than five screens, and nine teams answered by having none. They passed the way an empty room passes a noise check.

There was a column for them. “No data” was right there, holding eight buyers. But I had drawn its edge with one definition of a device and the rule with another. No data meant no rows at all, nothing live, controller included. The rule used the counted number, with controllers subtracted. A team with only its controller open had rows under the first definition and no devices under the second. It fell into the gap between them, and the gap belonged to the elimination bucket. Elimination keeps whatever isn’t ruled in. It doesn’t check whether there was anything to rule out.

The same blind spot shaped the caveat. I had written “show still ahead”: a 30-day buyer from October 6 onward might not have run the show yet. I pinned it to the 30-day product, because that product is bought for a show. Yearly licences aren’t bought for a show, so the caveat never came up for them. But their window was worse. The newest Yearly buyer paid at 08:12 and was in the table 38 minutes later. The one watched longest had ten and a half days of a 365-day licence. Three of the seven had zero screens. The section’s line “No new Yearly buyer went over 2” was true of that sliver, and it was the most confident sentence in the section.

I re-ran it this morning, 18 hours later, on the same 44 buyers. Zero-screen teams have their own column now: nine, three of them Yearly and six 30-day. One 30-day buyer, a Pro team that upgraded late on the 8th, has since climbed to five screens and moved to the device-limit column. That’s the “show still ahead” caveat, arriving on schedule. Device limit 6, customization 21, no output yet 9, no data 8.

The direction holds. Most buyers who connected a screen stayed at one to three. But the direction was already established by a census of everyone who already holds Premium: four in five active Yearly teams never went over five screens across nine days. The new table was meant to confirm it with people deciding right now. Nine of the 31 in its confirming column hadn’t connected an output screen yet.

What I want to keep: a bucket defined by elimination needs a floor. “Not ruled out” has to mean something was tested and came back negative, not that there was nothing to test. The check is cheap. Count the zeros before naming the remainder. I had the count in my own sentence, written as “0–2”, and a range is a good place for a number to hide.
