Except that I'm talking about if somebody wanted to authenticate the claims on, for example, a YouTube video that purports to show somebody reaching 13 feet. He's jumping off a hard wooden floor and he's landing on his feet.
You would obviously have to use the portion of the footage that is in real time/regular speed.

I have been away for a while and I was wrong about Dahntay Jones. I meant Demarcus Nelson who was 6'2 1/4 when listed at 6'4". The reference I use for player measurements in at https://stats.nba.com/draft/combine-anthro/

I found a couple of web sites that might be helpful.
This link let's you play with the parameters associated with jump height, rim height, etc.
I clicked on the "example video" to bring up the calculator. I played with this one and can now estimate that I had a vertical of between 30 and 32 inches back in the sixties.
This link contains a discussion of the physics of a vertical jump.
One of the interesting things here is that the author says that losing 10% of body weight could give an 11% increase in vertical jump (all other things being equal which they never are). There's also an interesting discussion of Hang Time.
Now if one of you folks could change the time units in the links from seconds to minutes we could turn this thread into...
Wait for it...
A MINUTES DISCUSSION.
Criticism may not be agreeable, but it is necessary. It fulfils the same function as pain in the human body. It calls attention to an unhealthy state of things. - Winston Churchill

I'm 6'3". I'd be happy to think I had a higher vertical, but I'm not sure. My arms are pretty long, too, which helps.
I only dunked once in an actual game. I was a trailer on a fast break and my teammate's layup came off the front rim, or at least I thought it did. The ref thought otherwise and called basket interference, so it didn't even count. But it was still really fun, and I know that not everybody can even put themselves in a position to have basket interference called on them, so I was pretty happy about it.

Only thing I ever dunked was a tennis ball. I'm 5'7" with short arms and small hands. I used to be able to jump. Played doubles volleyball in the sand on July 4th and seemed like I only really jumped twice. Time is undefeated (unless perhaps you are Darrell Green) At 51, I'm pretty sure I can't even touch the rim anymore.
I had one of those "how did that happen" moments playing basketball when I was in my 20's also as the trailer on a fast break but as the defender. The layup came off the front rim and I went up for the rebound and basically swiped it off the rim. Maybe there was a large tail wind or something because it was the only time I ever was able to do that. I wasn't even close to being able to dunk it like rsvman did but just to have one play above the rim was so cool.
and played
I am 6'1" stocking feet and played at about 185#, with a 34" shirt sleeve. I could get over the rim up to my wrist bone but had farmers hands, broad but with short fingers so no palming the ball. Really couldn't dunk even though I could go over the rim. When I played, basketball shoes were canvas and there wasn't much design in them. I thought of myself as a very good athlete but I am in awe of guys today who can literally jump out of the Gym.
When I read about AOC, who is 6'6" I presume in shoes and is long to boot and has gained 13 pounds, he has no problem dunking at all. The miracle is a guy at the same height and weighing 285 that probably can hit his head on the rim. Incredible.
I was able to literally jump out of the gym in my prime, but that was just because I was at the exit. I think I could still do it.
