Thank you very much for your very valid comment and for the reading!

I’ve updated the post to show how it would behave with multi-statement functions.

Sincerely,
Dmitri

First of all I should thank you for putting together well informative blog.

Now title of this post is confusing to me. Ofcouse, inline TVFs generally give very good performance (and matter of fact SQL optimizer loves it) BUT

It appears to me that you are trying to compare it with a scalar UDF (not multi statement TVF — multi statement TVF returns a table variable)

Agree, Multi statements TVS are as bad as scalar UDF (as they are also evaluated per row) but to me dbo.avgitemcost() is a scalar UDF contrary to the title of the blog post
