Compare an explicitly qualified oven-based starting point with your appliance instructions, and plan realistic batches.
Method and practical checks
The example reduction and early-check percentage are adjustable planning assumptions, not tested constants for every food. Checking early does not mean the food is ready.
Enter the load recommended for this food, not the appliance’s litre capacity. Crowding restricts air movement; use more batches rather than inventing a longer safe time.
Fresh and frozen foods, thickness, coatings and appliance designs need different instructions. Do not automatically use a fresh-food schedule for frozen food.
Check doneness using appropriate food-safety guidance. Cooking may take longer than the oven reference; the displayed window is not a safety limit.

This is an adjustable starting estimate, not a verified cooking schedule. Prefer food-package or appliance air-fryer instructions.

Known air-fryer instructions
Use a tested schedule for the actual food, fresh/frozen state and appliance. Calculate batches and elapsed time.
Batches run sequentially in one cooking chamber. Dual-basket or multi-shelf appliances need their own tested loading instructions; capacity alone does not establish cooking time.
The final batch may be smaller. Check it separately and follow instructions for shaking, turning, resting and food safety.
Worked example
An oven instruction of 200 °C for 30 minutes gives a starting estimate of 180 °C with the default 20 °C reduction. With 800 g of food and a 400 g load per basket there are 2 batches; the first check comes after 21 minutes (70% of 30), and the whole job takes up to 63 minutes including 3 minutes of preheating.

Reading the result
This is a starting point for checking, not a cooking time. Food is ready when it is cooked through, not when a timer ends.
Crowding the basket slows cooking. More batches is usually the practical answer rather than a longer time for one overloaded basket.
Frozen, breaded and very thick foods need their own instructions; use the package’s air-fryer directions whenever they exist.
