Fresh vs frozen
Ninja's manual separately lists a frozen roast potato figure: 700g at 190°C for 20 minutes. The Ninja and Salter figures above are for raw potatoes; Instant's is for par-boiled potatoes and is shown as a separate method.

Size and thickness adjustments
Ninja's fresh figure is based on 1kg cut into 2.5cm wedges, shaken partway through cooking (22 to 26 minutes); Salter's is close at 1.3kg for 25 to 30 minutes, also cut into 2.5cm wedges with 1 tablespoon of oil. Instant's figure (205°C, 20 to 25 minutes) is specifically for par-boiled potatoes, which may explain why its time sits in the middle of the range despite the higher temperature.
Browning and doneness
None of the manuals give a food-safety temperature for potatoes; look for a golden, crisp outside and a soft centre when pierced.
Where brands disagree
Instant's figure (205°C, 20 to 25 minutes) is for par-boiled potatoes, so it is shown as a separate method rather than widening the raw wedge range.
