01Every number has a source
Wattages, dry times, capacities and coverage figures come from the manufacturer's own specification page, and the page it came from is linked in the table next to it. Where a maker publishes nothing, the row says so rather than carrying a figure we invented.
02The arithmetic is shown
We compute running cost as watts / 1000 x hours x price per kilowatt-hour, using the EIA's published US average residential rate. The sum is printed so you can check it against your own utility bill.
03Prices are live or absent
A price appears only when it came from a verified live lookup in the last 48 hours, with the date it was taken. Past that, it disappears and the button reverts to 'Check price on Amazon'. We never print a remembered number.
04Our score is never rating markup
The score on a product card is editorial and we say so. It is deliberately kept out of the structured data, because publishing an untested opinion as a machine-readable product rating is the exact signal we refuse to imitate.
