I don't think we really talk about all profiles across channels, rather number of profiles in population X on channel C. So it not change counts at all.</div><div class="gmail_default" style="font-family:monospace,monospace"><br></div><div class="gmail_default" style="font-family:monospace,monospace">that said, for those analyses <b>that don't </b>partition by channel, they will be an induced artificial variation. In the last 30 days 0.4% of profiles had more than two channels. Hence apart from the usual variation in day to day, week to week, year over year counts of profiles, we are injecting an artificial change of about 0.4%.</div><div class="gmail_default" style="font-family:monospace,monospace"><br></div><div class="gmail_default" style="font-family:monospace,monospace">Something to think about.</div><div class="gmail_default" style="font-family:monospace,monospace"><br></div><div class="gmail_default" style="font-family:monospace,monospace">Regards</div><div class="gmail_default" style="font-family:monospace,monospace">Saptarshi<br></div><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Oct 16, 2017 at 9:31 AM, Alessio Placitelli <span dir="ltr"><<a href="mailto:aplacitelli@mozilla.com" target="_blank">aplacitelli@mozilla.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><span class=""><br><div class="gmail_quote">2017-10-12 15:11 GMT+02:00 Romain Testard <span dir="ltr"><<a href="mailto:romain@mozilla.com" target="_blank">romain@mozilla.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><div><div>Hi all,<br><br></div>We're planning on implementing
dedicated profiles per channel (bug 1373244), hopefully in Firefox 59,
to help address profile corruption issues our users can encounter when
using a profile previously used on a later version.<br></div>Once it
gets implemented we'll have more profiles on telemetry and it probably
impacts the interpretation we have of our telemetry data. A solution may
be to implement a correlation ID between different profiles although
