Having one product sold in 60 days can mean this is a lucky sale.
2
This is the default value for Relevancy Sales because with two product sales, you can rule out that this search term can really generate sales. Choosing this search term is a good idea because it is working.
3 to 5
Not impossible.
You are allowed to use values greater than 2 as you know best your business. Only you can decide whether it is feasible to calculate that sales is more than 2 in 60 days.
To understand how relevant a custom search term for a product is, you need to know how many sales the search term generated in a period of time.
