Need "Days Since First Session" definitions

Hello,

I am been tracking “days since first session” for a the conversions on a particular client’s website. Most of the time, it makes sense (0,1,5,38, etc.) but occasionally, I get one of these two:

N/A
9-14

What’s going on here?

Hi @David_Culbertson,

I think it would be best to see the whole report.

9-14 could be a grouping.

When it comes to n/a - this should explain it:
obraz

Hi @anthonybartczak,

But I don’t groupings for less than 9 and higher than 14. Last week, I had “days since first session” of 38.

The “n/a” is not consistent. The much more common combination is 1 session and 0 days.

You can send me the report URL in a private message if you don’t want to post the data here. I mostly want to see how it’s constructed (dimensions and metrics).

Is it different than the number of new visitors?

A correction and more information for you.

  1. correction - sometimes, the sessions number displays the range of “9-14.” Otherwise, it’s always a single number.

  2. Here are the 48 goal conversions during a single session last week. Six had “n/a” as “days since first session”
