I have an unintended variation on that...

Once a day, I have to press a button on my kitchen scale 4 times, to switch it from grams to fl.oz.

It seems that the the fastest tempo at which one can press the button 4 times... matches the "1-2-3-4" at the start of the song people might know from "JK Wedding Entrance Dance". https://www.youtube.com/watch?v=4-94JhLEiN0

(I have a different association with the sequence 4-3-2-1, reminding me of the Peter Schilling song. https://www.youtube.com/watch?v=wO0A0XcWy88&t=41s )
