Every figure in a Kibbo guide is checked against its original source before it's published. When a figure, deadline, or legal fact in a published guide turns out to be wrong, or changes after publication, the guide is corrected and the change is recorded here, newest first. Typo and formatting fixes aren't listed; changes to facts are.

What Does It Really Cost to Get Sick? US, UK, Germany & Spain Compared
What changed: Germany's "average time to a specialist appointment" figure was stated as 42 days; corrected to 36 days, in the article text, the wait-time comparison table, the downloadable dataset, and the related classroom exercise. The figure was also re-cited: it had been attributed to "Bundesgesundheitsministerium response to parliamentary question 2024 (via Ärzteblatt/ZDF/Pharmazeutische Zeitung)," a secondhand press citation; it's now cited directly to the official Bundestag document that contains it.
Why: The primary source, Bundestag Drucksache 21/3858, gives two genuine 2024 figures from the same government-commissioned insured-persons survey: 42 days is the average among patients who waited at least one day for an appointment; 36 days is the average across all patients, including those seen the same day. Our row is a general, unqualified proxy metric (paralleling the equivalent US figure, which carries no same-day exclusion), so 36 days is the correct match. The dataset's downloadable CSV was also reduced in this update to remove figures from several other sources whose own terms don't permit open redistribution (see the dataset's README for the full list); those rows keep their citation and a link to the source, with the value left for readers to get there directly.

How to Claim Compensation from Royal Mail for a Lost or Damaged Parcel
What changed: The compensation cap for Royal Mail Tracked 24 / Tracked 48 was stated as "up to £100"; corrected to £75.
Why: Royal Mail's own Tracked 24 product page states "Compensation cover up to £75" directly.
Source: Royal Mail, Tracked 24.

Evri Says Your Parcel Was Delivered But You Don't Have It?
What changed: The article told readers they could escalate an unresolved Evri complaint to POSTRS (the Postal Redress Service) after a deadlock letter or 8 weeks. That's corrected: Evri is not a POSTRS member, so that route isn't available — the article now points to a card dispute or continued escalation with the retailer instead.
Why: POSTRS covers Royal Mail only. Searching CEDR's own "Companies Covered" tool for "Evri" returns zero results (a search for "Royal Mail" on the same tool returns one, confirming the search itself works).
Source: CEDR, POSTRS Companies Covered.

DPD Lost or Damaged Your Parcel?
What changed: DPD's standard compensation cap was given as "£50–£100" in one place and "commonly around £50" in another; both corrected to £100. The 28-day evidence deadline was described as running from the dispatch date; corrected to run from DPD's request for evidence, not from dispatch (the 14-day notification deadline is the one that runs from dispatch).
Why: DPD's own Standard Terms and Conditions of Carriage state the cap as "£100 per Expresspak, Parcel, Freight Parcel or Shop Parcel" (Condition 11) and the 28-day evidence window as running "within 28 days of request for such evidence" (Condition 13), separately from the 14-day dispatch-based notification deadline.

How to Claim Compensation for a Lost or Damaged DHL Parcel
What changed: DHL's default air-liability cap was given as "roughly 22 Special Drawing Rights (SDR) per kilogram — $28-30/kg", with a worked example of "$55-60" for a 2kg parcel; corrected to 26 SDR/kg (~$35/kg, ~$70 for 2kg). Also removed a claim that damage claims specifically have a 14-day deadline; DHL's terms set a single 30-day deadline (from shipment acceptance) for all claims, with no shorter carve-out for damage.
Why: DHL Express's own Terms and Conditions of Carriage (valid 28 December 2024), Section 6.1, state the air liability limit as "26 Special Drawing Rights per kilogram (approximately $US 35.00 per kilogram)"; Section 7 states "All claims must be submitted in writing to DHL within thirty (30) days from the date that DHL accepted the Shipment", with no separate damage-specific deadline.

How to File a UPS Claim for a Lost or Damaged Package
What changed: The article described UPS's filing window vaguely as "60 days for international shipments" with "longer windows" for lost domestic packages. Corrected to a single, unambiguous figure: 60 days from the scheduled delivery date, for both lost and damaged packages.
Why: UPS's own "File a Claim" page states: "Start a claim within 60 days of the scheduled delivery for packages that have been lost or damaged, or if a collect on delivery (C.O.D.) payment wasn't received."
Source: UPS, File a Claim.

What Does It Really Cost to Get Sick? — Classroom Exercises
What changed: The teacher answer key gave the 2025 ACA out-of-pocket maximum for self-only coverage as $9,450.
Correction: The 2025 limit for self-only coverage is $9,200. $9,450 was the 2024 limit.

What changed: Data-quality fixes across three dataset files, made ahead of building classroom exercises on them. Streaming Pricing Dataset: corrected a rounding error in
percent_changeon 4 rows (Prime Video monthly membership, Prime Video Ultra, Apple TV+ Standard, ESPN+), flagged Prime Video's "Annual membership" rows as annual rather than monthly prices, and updated the README to describe both of the dataset's confirmed ESPN pricing gaps instead of one. US Airline Reliability Dataset: split the single CSV (which stacked three tables and broke spreadsheet/pandas imports) into three files — the main ranking, a year-over-year comparison, and Spirit Airlines' monthly on-time rate — moved its source citation into a new README, and documented the tie-break order behind the composite score so it can be reproduced from the published data. Healthcare Cost Dataset: corrected a note on the US appendectomy Layer C row that incorrectly claimed it was the Layer B source for the US base case, contradicting its own layer label and the article, which uses separate CMS-sourced figures as the US's Layer B. No headline finding in any of the three investigations changed.Why: A pre-publication data-quality pass ahead of building classroom exercises on these datasets, where every derived value needs to match the underlying data exactly.
Clarification: The US Airline Reliability Dataset's README originally described its
bumped_per_10000tie-break order as drawn from the airlines' underlying DOT figures at finer precision. That's not accurate — the unrounded values used to build the original ranking were never retained. The order published in the README was reconstructed after the fact by finding the one ordering that reproduces all 9 publishedcomposite_scorevalues exactly; the README has been corrected to say so. -
What Does It Really Cost to Get Sick? US, UK, Germany & Spain Compared
What changed: Corrected several figures in the section on the US healthcare system and the ACA. The December 11, 2025 Senate vote on extending the enhanced premium tax credits had four Republican senators in favor, not two, and the article had mixed this up with a separate House discharge petition. Removed a "114%" premium figure that had been attributed to the Congressional Budget Office and could not be verified; the article now says analysts projected that average premium payments for subsidized enrollees would more than double. The CBO estimate of 4.2 million more uninsured people now reads "by 2034" instead of "2034–2035". The Medicaid expansion count is now 40 states plus the District of Columbia, not "41 states", and we removed a statement about the political control of the ten states that have not expanded Medicaid, which we had not verified. We also added the January 2026 House vote (230–196, with 17 Republicans in favor) and the status of the Senate talks.
Why: After publication, the figures in that section were re-checked against reporting from Health Affairs Forefront, CNBC and CBS News, and against KFF's Medicaid expansion tracker. Several did not match those sources. The information about the status of the tax credits reflects reporting up to spring 2026.

Trapped in a Subscription? The Legal Phrasing That Forces Stubborn Companies to Cancel Your Account
What changed: Removed the citation of the FTC's 2024 Click-to-Cancel amendments as current law. The article's legal-phrasing guidance and its sample escalation letter now cite the FTC's Negative Option Rule instead.
Why: The Eighth Circuit vacated the 2024 Click-to-Cancel amendments in July 2025, and the FTC's February 2026 final action restored the Negative Option Rule as it stood before them. Citing a vacated rule in a demand letter would have undermined the letter.
-
The Subscription You Thought You Cancelled: What to Do When the Charges Keep Coming
What changed: The paragraph on reporting a company to the FTC no longer presents the Click-to-Cancel rule as adopted and in force; it now states that the rule was vacated.
Why: The Eighth Circuit vacated the 2024 Click-to-Cancel amendments in July 2025.
-
The Fine Print That Signs Away Your Rights: Forced Arbitration and the Click You Don't Remember
What changed: Two paragraphs that described the Click-to-Cancel rule as active and "still being appealed" now state that it was vacated and that the FTC has restarted the rulemaking.
Why: The Eighth Circuit vacated the 2024 Click-to-Cancel amendments in July 2025, so the rule was no longer under appeal or in force.
-
Cancellation Letter Pack (template)
What changed: The product description no longer presents the FTC's 2024 Click-to-Cancel amendments as current law; it now refers to the FTC's Negative Option Rule.
Why: The Eighth Circuit vacated the 2024 Click-to-Cancel amendments in July 2025.

Which US airline performed worst in 2026? We ranked all 9 on the DOT's own data.
What changed: Removed the statement that Spirit Airlines was in an ongoing merger process with Frontier, and added an update note at the top of the investigation.
Why: The merger statement was wrong: Spirit ceased all operations on May 2, 2026 and entered liquidation after failing to secure a federal bailout.
