Segment Sorting Order / Queue

Your software
My Mautic version is: 4.4.8

Your problem
My problem is:
Hi everyone. Does anyone know, how email sending is ordered in a segment? E. g. my segment contains 100 contacts, and I set up a cronjob to send only 10 mails each day. Which conditions apply here for mautic to decide which contacts would get the first 10 mails?

In Slack I was given this answer: “order of contact IDs in ascending order”. Can someone second that?
