***The cadence and arrangement for Biden doesn’t seem like either an inaugural 21 gun salute or a funeral salute.

~~~~~~~~~~~~~~~~~~

According to AR 600-25, Chapter 3-3 the cadence for a cannon salute is as follows:

(6)b. Cannon salutes to persons.
(1) The time interval between rounds in a cannon salute will be three seconds except as follows:
(a) When honors are rendered at funerals, in which case the cannon salute will be fired at five second intervals.
...
(2) The firing of a salute will begin at the time the person entitled to it enters the installation.

However, as noted in the Arlington National Cemetery Blog: https://www.arlingtoncemetery.mil/Blog/Post/12870/Presidential-Salute-Battery-Honors-Dignitaries-and-Events

“For a visit from a dignitary such as President Lasso (President of Ecuador), a communications representative in the lead vehicle radios Capt. Nathan Lundquist, the battery officer in charge, as the vehicle passes by McClellan Gate. That starts the firing sequence. “We found through trial and error,” explained Lundquist, “that nine seconds is the interval spacing that gets the last round fired as they get to the Tomb.””

Hope this helps to clear up at least part of the situation.

I would say "case closed."
