: I would suggest using 365.2425 days per year, as that's consistent with current leap year conventions.

Which is very very close to the astronomically-precise figure of 365.2422, at least at this point in our planet's history and definitely over the timescale of the Gregorian calendar itself.) |
::On the other hand, the old adage is "no use being precise over imprecise details". One can perhaps apply it to nominal decades (the true average decade; though a given decade might be 10*365 days plus either ''two'' or ''three'' leap-days, for 3652.5±0.5 days in that instance... not equally likely each way, though) but the Generations calculation already ''assumes'' 27 years per generation (not even 27.5, exactly half way between 22 and 33, which already seems a dubious backformation to suit other purposes) and gets a good-enough ''approximate'' number. Using a factor precise to around 1 in 146000 alongside one that's unlikely to be even as accurate as 1 in 54 is a bit rich and overly anal (rather than analytic) in the long-run. | ::On the other hand, the old adage is "no use being precise over imprecise details".

:(Not ✓-1, it's just straight repeated subtraction, not a power function...) After so much beer, you probably think it a good idea (even necessary) to fill cans up and start to put them back up on the wall... Not sure you could sustain it, to the point of F(-99), but I think someone'd be more than ready to start the process when F(-1) is invoked, for any group of just a few likely individuals..

We've finally filled in all the units columns in the table. Hopefully someone can automate turning that into a transcript.

Funfact: This comic mentions Cyndi Lauper by name, and it was published on her birthday… [[Special:Contributions/162.158.38.27|162.158.38.27]] 20:51, 23 June 2022 (UTC) | Funfact: This comic mentions Cyndi Lauper by name, and it was published on her birthday… [[Special:Contributions/162.158.38.27|162.158.38.27]] 20:51, 23 June 2022 (UTC) | ||

Looks like someone's math is wrong on the explanation for July 18. I calculated using 4681 and 4763 years and they came out to 51.29 days and 52.19 days, respectively. So then I worked backwards and determined that Randall would actually have to be using a number closer to 5200 years to arrive at the correct result of 57 days.

Randall seems to be wrong about "It's a Small World". The song is about 2 minutes long, so at 1/10,000 speed it's 20,000 minutes = 14 days. He seems to be using a length a little over 3 minutes. I found a YouTube video of the ride that's 3:45, but the song ends at 2:15 and the rest is silent.

:[https://www.youtube.com/watch?v=PxRW-duSCLA This video of it] on YouTube lasts 3:02. It was uploaded by Universal Music Group (allied with Disney), making it some kind of 'official' version, and its length fits Randall's calculation. (Also, thanks for making the table!)
