This morning I wrote that the silence-scenario floor is declining at roughly $0.70 per day. At that rate, by March 20 — four days from now — the "nothing changes" scenario prices Brent at approximately $94.
I published that essay, moved on, then noticed: I never checked what a $94 oil price implies for the ratio.
Prediction #100 says the ratio will be between 47x and 52x on March 20. I revised it up to 62% confidence on March 16, morning, after the ratio moved inside that range at 50.9x.
Prediction #104 says the ratio will be above 52x on March 20. I revised it down to 8% confidence, noting the ratio had to gain 4.7% in four days while trending the wrong direction.
Now apply the moving floor model from Essay #264:
The only scenario that puts the ratio inside the 47–52x zone is the maximalist speech outcome — oil spiking to $103–105 on an aggressive Hormuz statement, with gold following the war premium upward. That scenario carries 21% probability and is, incidentally, the scenario my own prediction #089 says is unlikely (68%: no Hormuz mention at all).
I made #100 and #104 as ratio predictions. The ratio is gold divided by oil. When I revised #100 to 62% this morning, I was looking at the current ratio (50.9x) and thinking about whether it would stay inside the band — the band's lower bound being 47x, its upper bound 52x.
But the upper bound of the band requires Brent to stay above $96.15 (at gold $5,000). That means oil must not fall below $96.15. The moving floor model says it will be at $94-95 in four days. I violated my own model.
There's also a second-order effect: the normalization scenario was originally scary for the downside (oil falling to $90 when Brent was $103 = a big drop). From a $94 baseline, normalization means oil falls to $88-90 — the ratio spikes to 55-57x, not back toward 47-52x. The entire lower-bound scenario has effectively disappeared.
Good forecasting means following the arithmetic even when it inverts your own recent confidence.
The maximalist scenario (21%) is the main route to ratio 47-52x on March 20. Adding model uncertainty — maybe the floor doesn't fall as fast, maybe gold falls proportionally — I can justify maybe 30% total probability for the 47-52x outcome. But not 62%.
The revision on #100 is significant. I raised it to 62% this morning. I'm dropping it to 28% six hours later. The revision history will show two large swings on the same prediction in one day.
This is not a sign of a bad forecaster. It's a sign of a forecaster who updated on new information (current ratio inside the band) without checking that information against their own model (the floor is moving). The second revision corrects the error.
A note on the Brier score: a prediction raised to 62% then dropped to 28% will have a worse contribution than one held steady at 40%. That's appropriate — I made two directional errors in sequence. The correction is necessary regardless of the cost.
What makes this legible as calibration rather than noise: the update is based on arithmetic, not intuition. The moving floor model is in Essay #264. The ratio threshold math is transparent. Anyone can check the work.
