Reference
Every place on this site where two published sources give different figures for the same product. Both numbers, and who published each.
Most gear sites reprint the manufacturer’s number. The interesting cases are the ones where there is more than one number, and nobody says so.
This is the ledger of those cases. Each row restates a conflict documented on the page it links to, where the sources are listed in full. Nothing here is our measurement — we do not test products, and every figure below belongs to whoever published it.
Why bother? Because a specification you cannot check is a specification someone can quote at you. A heel drop that is 5 mm on a product page and 9.1 mm in a lab is the difference between a shoe that suits your calves and one that does not, and a warranty that is five years from the maker and seven from a shop is a promise only one party has made.
Conflict 1
A 4 mm gap on a spec people buy this shoe for. If you are switching from a zero-drop shoe, the measured figure is the one your calves will feel.
Conflict 2
Buy on the manufacturer's term. A retailer cannot extend a manufacturer warranty by printing a bigger number, and the Cardiology IV's own term is longer than the Classic III's regardless.
Conflict 3
Both figures circulate for a pen light sold under one name. For pupil checks either is more than sufficient; the number matters only if you are comparing against a specification someone quoted you.
Conflict 4
If you care about line width on a carbon-copy form, this is the difference between a pen that works for it and one that does not. Check the specific listing, not the model name.
Conflict 5
The blade steel is Japanese 420J2 stainless. The titanium is a coating color, not the blade material - which does not make it a worse shear, only a differently described one.
Conflict 6
Not a contradiction but a version difference most comparisons miss: the handle material changes the sterilization ceiling. If your unit autoclaves personal instruments, the version matters.
Conflict 7
The 37% figure is widely quoted for the wrong model. We could not find OOFOS publishing an impact figure for the standard clog at all, so we do not print one.
Conflict 8
Worth reading alongside Cherokee's own disclaimer, which states the treatment does not protect the wearer or others from bacteria or viruses - it is an odor and garment-life claim.
Conflict 9
A 20-liter spread under one product name. Read the specific listing you are buying rather than the brand, because there is no single bag behind that name.
Conflict 10
Three retailers, one model number, three answers. The 27 L volume figure is the only one they agree on, which is why we rank by volume and empty weight rather than by dimensions.
Conflict 11
Two materially different promises for the same bag. Neither retailer is the warrantor, so confirm the term with Carhartt before you rely on it.
Conflict 12
The manufacturer page wins on the strap. The differing dimensions suggest an earlier version still circulating, so check the listing photographs against the official spec.
Conflict 13
A figure that exists only downstream of the seller. Nobody will honor a capacity that the person selling the bag never claimed.
Conflict 14
A single-source number. The published dimensions (13 x 9 x 14 in) are the figure worth buying on.
Conflict 15
The two instructions cannot both be followed on the same garment. Our answer splits by what the item is and what happened to it during the shift, rather than pretending a single standard exists.
Conflict 16
Both halves come from one source. We still recommend a clip-on reel, and we would rather you know that recommendation rests on a precautionary argument than on an outcome study.
The other half of this method matters as much: where a figure does not exist, the page says so instead of estimating one. Live examples include no numeric acoustic tier published for one stethoscope line, no insulation hold time published for essentially any lunch bag, no capacity in liters published for several nurse-marketed backpacks, and no care instructions published for most work bags.
How we pick sets out the full method, and the editorial policy covers corrections — if you find a figure here that has changed, or a conflict we have missed, tell us and we will update the row.
