[mat-wg] Fast-paced RIS beacon changed schedule unexpectedly

Hi Ben,

You are not losing your mind :-)

While preparing the changes for February 1st we spotted an anomaly in 
the fast-paced beacon schedule. The beacon is supposed to be announced 
every 10 minutes and then withdrawn every 10 minutes. As you mentioned 
below, the description of the old schedule was "Announcements at XX:10, 
XX:30, XX:50". However, due to a software issue the announcement at 
23:50 was actually not implemented. Because of this there was a 30 
minute gap each day between 23:40 and 00:10.

Since the announced changes on February 1st required us to stop all 
announcements, we used the opportunity to fix this issue. The existing 
announcements were shifted by 10 minutes in the process. The schedule 
mentioned on the website (Announcements at XX:00, XX:20, XX:40) now 
matches what is implemented.

Apologies for not explicitly mentioning this.

Kind regards,
Martin
