Methodology

Every specification on this site is stored in one of six states, and we use the same six words everywhere — the product page, the comparator, the Finder, and our guides — rather than looser language like "verified" that could mean something different in each place.

The six states

• Confirmed — read directly from the primary source page itself, at the time it was checked.
• Archived source — the value came from a primary source that has since gone offline (a 404 or similar). We keep the data and the checked date, but the source link is shown as plain text, never a live link, since it no longer resolves.
• Estimated — the figure comes from a search result or snippet describing the source page, not a direct read of the page itself.
• Conflicted — two or more sources disagree and we haven't picked a winner; every candidate value is shown with its own source.
• Not verified — nobody has found a value yet. We never fill this with a plausible guess or leave it blank in a way that could be mistaken for a real value.
• Not applicable — the field structurally doesn't apply to this product (a corded model has no battery spec to report).

As of this catalog's current research pass, every sourced spec on this site is at "Estimated" confidence, except the two WYBOT models with an "Archived source" (see below) — none has yet been verified by a direct fetch of the live page. This is a limitation of our current research tooling, not a claim that the data is unreliable: a further, direct-page verification pass is a planned improvement, not something we present as already done. When you see the word "documented" in our guides or product pages, it means a spec has a value and a cited source — it is not a claim that the source was read directly (that specific, stronger claim is what "Confirmed" is reserved for, and nothing on the site currently carries it).

Source hierarchy

We prioritize sources in this order:

• The manufacturer's own product page, for the US market where available.
• A retailer listing (currently Amazon) when the manufacturer doesn't publish a given spec — clearly labeled as a retailer source, not treated as equivalent to the manufacturer.
• Independent/secondary sources are used only to flag a contradiction, never to replace a primary source that already gave us an answer.

Archived sources

When a manufacturer page we sourced data from later goes offline, we don't delete the data or quietly swap in a different URL — we mark the source archived. The spec, its original citation text, and the date it was last checked all stay on the record; only the link itself stops being clickable, since it no longer resolves. The WYBOT M1 and M2 pages are currently in this state.

When sources disagree

When we find a manufacturer spec and a retailer listing giving different numbers for the same product, we use the manufacturer's figure and keep the disagreeing listing visible on the product page as a flagged discrepancy ("Conflicted") — we don't average them, and we don't silently pick one without saying so.

What we don't track

We deliberately don't store or display prices, star ratings, review counts, or sales figures anywhere in our catalog. Those change too often for a static page to keep accurate, and mixing them with our source-cited specifications would blur the line between what has a citation and what doesn't.
