Hi Baba, and welcome,
You’ll find quite a few other threads here which point out that the number of items is almost meaningless, especially for comparing one a-v product to another, simply because (unfortunately) there’s no standard or agreement in the “industry” as to how to count them.
I’m sure Alwil has an “official” number posted somewhere – but keep the above in mind, that it’s just one company’s interpretation of how to count them.
Best,
Mike
