Using Visit vs Hit in segment definition yields different visit coverage

[Royyyyy]

when I define a segment on AA, I thought the difference between picking the Visit vs Hit is the visit will include all the records in that visit while hit only includes the matching records. However, I do see the visit coverage also changed for some reason: If I change this example segment from Hit to Visit, the visit coverage changed from 115 to 158 on the top right stats panel. I'm wondering why this would happen? My assumption was the two settings should yield the same visit coverage.

For the HIT all of the rules needs to be TRUE in the HIT itself. So only visits where ALL the rules are met in SAME HIT will be picked up.

For the VISIT all the rules needs to be TRUE during the VISIT lifetime so one or more HIT can contain one or more rule to be TRUE. 

i.e :

RULE  1 evar1 = 123

AND 

RULE2 evar 2 =123

AND

RULE 3 evar3 = 123

VISIT 1

HIT1 evar1=234,evar2=123,evar3=123

HIT2 evar1=aaa,evar2=aaa,evar3=aaa

HIT3 evar1=123,evar2=aaa,evar3=aaa

VISIT 2

HIT1 evar1=123,evar2=123,evar3=123

HIT2 evar1=aaa,evar2=aaa,evar3=aaa

HIT3 evar1=aaa,evar2=aaa,evar3=aaa

VISIT 3

HIT1 evar1=234,evar2=234,evar3=234

HIT2 evar1=aaa,evar2=aaa,evar3=aaa

HIT3 evar1=123,evar2=aaa,evar3=aaa

VISIT 4

HIT1 evar1=123,evar2=234,evar3=234

HIT2 evar1=aaa,evar2=123,evar3=aaa

HIT3 evar1=aaa,evar2=aaa,evar3=123

HIT SEGMENT == 1 VISIT

VISIT1  ==> All evar meet at some point the required values but not in same hit

VISIT2  ==>All evar meet rules in same HIT

VISIT3  ==> Not all rules met

VISIT4  ==> All rules matched but not in same HIT

VISIT SEGMENT == 3

VISIT1  ==> All evar meet at some point the required values but not in same hit so in same VISIT

VISIT2  ==> All evar meet rules in same HIT so in SAME VISIT

VISIT3  ==> Not all rules met

VISIT4  ==> All rules matched but not in same HIT so in SAME VISIT

If you modify you VISIT segment to have visit at top and add a container that uses HIT and put all rules inside this container I would think you should get same visits as in segment with top container as being HIT.

Hope this helps
