Visit Segments and Visit Participation Attribution

[C_Hasson]

Hi all,

I'm trying to understand why revenue would be different using these methods. 

If I am looking at email channel and create a Visits based segment - revenue would be 100k. 

If I create a visit participation revenue metric - revenue would be 70K. 

If participation allocates 100% revenue to each point then why is it less than when its segmented in a visit?

Thanks
