File Downloaded - which is the right way to measure?
Good day everyone,
May I have your help to clarify the right way to measure File Download?
I can see 3 ways:

1. Activity Map Link with Activity Map Link Instances
2. Dimension Download Filename:
i. use "Download Filename Instances"
ii. use "File Downloads" - our custom defined event
As you can see, they are giving significant different result.
May I know which is the right one? and Why they are so different?
Thank You.
