Unexpected discrepancy

Hello everyone !
We have some events with the 'record once per visit' type and use them as default counters.
I compare one record once per visit event with visits metric(using segment on hit with the values in CustomLink and Products dimensions). In most cases, difference between this 2 methods is really small, like < 3%, but in some urls it can be more than 30%, what may be the reasons of that ?
Is it correct to compare these metrics and how does Adobe Analytics calculate values of the 'record once per visit' events ?

Dear AMinakov,

Do not compare the event (with record once per visit) with the visits while you break it down with the dimensions.

Let's see the example: In a visit, URL1 triggers the event, URL 2 triggers the event and URL 3 triggers the event.

Because you set the configuration of the event to 'record once per visit', the event is recorded during the first event i.e. against URL 1. However, the same won't be captured against URL 2 and URL 3 (But visits will be recorded for all 3 URLs).

Now, if you compare the visits and event against URL1, it will be a perfect match. But not for URL2 and URL3.

@aminakov You can use "Single Access" metric against a specific dimension and compare it with your report

 

Here is the documentation on the same

    Dear Pratheep Arun Raj B (Arun),
    Thank you for your answer !
    I understand your example, but what I'm doing is a little bit different and that's why I was surprised.
    Let me try to explain : I compare 'record once per visit' event with the visits with the special condition on the custom link on hit. That's why I expect to see the same numbers while breaking down with the urls dimension.
    And the strange thing is that I see difference only in a few URls.
