I was watching both streams side by side; SpaceX was even quieter than before, and the NSF performed a very professional job of providing that much-needed but restrained narration. Good job.

Note that SpaceX seems to have screwed up with the booster flight history (or that there was a late change) - after liftoff the mission page now shows B1058, not B1060, as the one that handled today’s launch. Still a record-breaking 17th launch for a single Falcon 9/Heavy 1st stage, but not the one originally claimed.

Quote
This is the 17th flight for the first stage booster supporting this mission, marking the first Falcon 9 booster to reach this milestone. It previously launched Crew Demo-2, ANASIS-11, CRS-21, Transporter-1, Transporter-3, and 11 Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas, which will be stationed in the Atlantic Ocean.

Some reusability stats for this launch (Starlink Group 6-17):

Booster B1058.17 turnaround time: 71 days 23 hours 40 minutes
(its previous mission was Starlink Group 6-5 on Jul 10, 2023 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 56.60 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-40 turnaround time: 3 days 23 hours 59 minutes
(the previous launch from this pad was Starlink Group 6-16 on Sep 16, 2023 UTC).

It's currently the 2nd best turnaround time for this launchpad
(the record is still 3 days 22 hours 26 minutes between Galaxy 37 and Starlink Group 6-8 launches in August 2023).

FYI: median turnaround time for SLC-40 is currently 7.40 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet online.
