7 foods on this site have no figure for the AF140UK

The table stops where its sources stop: nothing on file says anything about burgers, fish sticks (frozen, breaded) or frozen pizza in this machine. If you've cooked one of them in yours and know what works, that measurement exists nowhere else — it can't be looked up, derived or generated, only cooked.

Fill one of these gaps

Takes about a minute — this appliance arrives already selected, and only the temperature and the time are required. Nothing publishes straight away: every submission is moderated first.

What these specs mean against the other 37 models on file

Power and size. At 1750 W, the AF140UK ranks 13 of 38 for power on this site, where the median is 1700 W and the corpus runs from 900 W to 3040 W. Its 4.7 L sits below the 6.8 L median, and 23 other models here share its single basket layout. Those two figures are how the calculator narrows down a machine for someone who doesn't know their model code. Neither is a cook time on its own, and nothing on this site converts one wattage into another.

What the dial reaches. ~410 °F is this model's ceiling — 15 of 38 on this site, where the lowest ceiling on file is ~392 °F and the highest ~480 °F. Every food on this site has a reference temperature at or below that, so none of them is out of range for this machine.

How much it is documented to hold. The heaviest single batch Ninja's own chart describes for this model is 1000 g of chicken wings (22–26 min at ~392 °F); the lightest is 460 g of steak. 2 rows in the table above state no weight at all, because the manual gives none. A time without a portion size can't honestly be scaled to what you are actually cooking, so the column is left empty rather than filled with a plausible figure.

Long or short against everyone else. Most foods in the table above also appear in other manufacturers' manuals. Lined up against them, this model's published times land 10 inside the band the other charts cover, 0 shorter than anything else published, and 1 longer.

Chicken Nuggets (Frozen) — 20–22 min at ~392 °F here, against 8–16 min across 24 other charts from 10 brands. This one is the longest of them.

None of those is wrong, and none is corrected here. Each is what that manufacturer prints for its own machine; how far apart they get is the subject of the register of disagreements, and what the single basket format contributes to it is set out separately.

Why your time might still differ

Manuals contradict each other constantly, and we keep the receipts rather than smoothing them away: where the manuals disagree, what a single basket design does to the times, and how every figure here is sourced.
