We guarantee good results whenever the object to be recognized covers at least 20% of the scene.

However, it is important to note that this refers to the part of the object that is visually characteristic for that object. For example, a typical bottled drink can be distinguished from other objects (bottles) due to its label containing its name and some characteristic visual patterns.

Therefore, a drink bottle will be reliably recognized when its label covers at least 20% of the scene depicted in the query. Therefore, whenever your use case involves recognition of objects that may be far away it is a good idea to guide users to get closer to the objects, or zoom in, before snapping pictures.
