After Layton Lewis told all the sentinels to be ready for matching, he also gave them time to go to the matching center.
The data collected by the matching center could is connected to all the matching centers across the federation so as long as they wanted to be matched with a certain person at that time even if they aren't on the same planet, it is still possible.
They would only need to be in the same place when registering for marriage. So, it is still pretty convenient to have matching tests for a lot of people in the federation.
Ryzel rested well for two days as Layton Lewis would always bother him at night-time. Knowing that he won't be working their night activities would always happen for a long time. So, he was well rested as he would wake up late and only browse for news and other things with his light brain without doing other anything else.
In the day of Lyre's matching tests, Ryzel called Lyre as soon as he finished having his brunch.
