The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current understanding of physics.
I’d argue that a more precise timing like 53.8 minutes is more attention grabbing. It shows finer grained control of technology; a “look here! we can do this too!” sort of demonstration.
If we are the “more advanced” neighbor; then I could see that being done.
Such a cycle is a cycle like any other. It’s not “more precise” when it’s shorter.
We attribute the 53.8 according to our scale.
