A changing survey base can make disruption look smaller than it is

Original research record

We compare the OTR data's four-day Gulf operational CSV with the original official releases. Gas shut in rose from 1,127 to 1,259.2 million cubic feet per day between October 8 and 9, a rise of about 11.73%. Yet the reported shut-in share rose only from 57.35% to 58.84%. Dividing volume by share gives an implied expected-production base of about 1,965.13 versus 2,140.04 million cubic feet per day. We cannot tell from this alone whether the reason is a changing expected base, survey detail or a source error. The new signal is that percentage movement alone is an unreliable measure of how fast this disruption grew.

• We would keep the original volumes, percentages and report timestamps together. • We should flag the discrepancy for clarification rather than silently repair a source or treat it as proof of misconduct. • The practical action is to compare absolute operating volumes alongside percentages before linking the data to deliveries, costs or investment forecasts.

A source clarification, corrected figure or disclosed change in reporting base could explain the difference. Rounded percentages alone cannot explain the whole derived-base gap, but the records remain estimates.

We see a strong data-quality reason to avoid a simple fixed-base percentage comparison over 48 hours. We would seek clarification and use both volume and share until the basis is clear.

Bayesian · what changed the estimate? Subjective estimate: 76% for this narrow claim: A fixed-denominator interpretation of the October 8-to-9 Gulf gas percentages will remain unsupported without a clarified or revised source record at the check time. We use the newly checked facts and the proposed mechanism to update a subjective judgement. We have not fitted a historical prior or measured likelihood ratios, so this is not a calculated Bayesian posterior. de Finetti · are the comparisons fair? We group copied reports and repeated OTR editions into the same evidence family. We do not assume events from different places are interchangeable or count them as independent confirmations. Kolmogorov · do the numbers agree? The stated event and its non-occurrence form a yes/no partition for this operational check. The opposite probability is 100% minus the stated estimate; this does not mean bullish and bearish. Missing outcome evidence remains unresolved rather than scored as success. These coherence checks do not establish calibration. The observed volume/share inconsistency also prevents a fixed-base percentage interpretation until the source basis is clarified.

V51 four-day numerical CSV + V51 source-change ledger + OTR Mega operating estimates; October7-9 original official pages independently opened.

This is an arithmetic audit of an operating series. The figures are not prices, and we do not describe the rise as an asset-return pattern.

No investment direction is assigned. We combine the observations into a General synthesis; no earlier frozen version of this exact claim was verified.

Public narratives may shorten the story to a single announcement. We distinguish the recorded event from our proposed mechanism and future check. We do not claim a measured public sentiment share.

No verified completed outcome record was found for this exact synthesis. We do not assign a past hit rate or treat an operating history as forecast success.

What past price moves show

This is an arithmetic audit of an operating series. The figures are not prices, and we do not describe the rise as an asset-return pattern.

Evidence against this view

A source clarification, corrected figure or disclosed change in reporting base could explain the difference. Rounded percentages alone cannot explain the whole derived-base gap, but the records remain estimates.

Why the direction changed

No investment direction is assigned. We combine the observations into a General synthesis; no earlier frozen version of this exact claim was verified.

What people say vs the facts

Public narratives may shorten the story to a single announcement. We distinguish the recorded event from our proposed mechanism and future check. We do not claim a measured public sentiment share.

How past forecasts performed

No verified completed outcome record was found for this exact synthesis. We do not assign a past hit rate or treat an operating history as forecast success.
