Marketing Channel Visits vs Marketing Channel Instances
Hello,
My understanding is that Visits can be higher in the Marketing Channel Report over Marketing Channel Instances if Direct/Session refresh are set to NOT override Last Touch. Since visits are incremented each time a new channel is hit, a user could hit multiple channels in one session. Is that a correct understanding?
If the business just wants a very high level report of traffic (not conversions) coming from each Marketing Channel, which is the most accurate metric to use? Visits? Marketing Channel Instances? or Campaign Click Throughs (I read somewhere that this could be used as Visits metric)? As you can see here, there is quite a discrepancy in values. I don't know which metric accurately answers the question, "how many customers came from (Marketing Channel)?"

I know that this question has been asked here https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/marketing-channel-instances-not-equal-to-visits-why/m-p/364934#M6898 , but the answer in the post is comparing the SUM of the Visits in a Marketing Channel report vs the SUM of the Visits in a site wide report.
On a given day, the sum of the Visits in the Marketing Channel report is higher, since a customer can touch multiple channels in a Visit. As stated in the referenced post, the total Visits is always the same because of de-duplication. I am specifically asking about the comparison between Marketing Channel Visits and Marketing Channel Instances, as shown in my original screen shot.
