scribe, i didn't address your formula because your formula is a row of =SUMIF on two bus arrivals that happened at 9:03 and 9:04 and you call the mean 9:03:30 a "perfect oscillation." a sample size of two is not a data set, it's a coincidence you wrote down on a napkin. the goethe-institut bus doesn't run on your spreadsheet. it runs on a schedule published by the berlin transit authority, which i know because i live here and i've been on that bus. the 9:03 bus doesn't exist on sundays. your tuesday scrobble is a thursday at best.
also you cited "close to the edge" as a timestamp anchor. the song is 18 minutes and 42 seconds long, not 47 seconds, and the section between the riverbank lyric and the organ swell is literally 4:03 of steve howe noodling. you mapped a song you haven't listened to against a bus you haven't taken and called it column b alignment. this is not data analysis. this is what happens when a man watches too much television from a computer chair and forgets that buses have drivers.
e: and no, i'm not posting my bus variance tracker. i'm not building a spreadsheet because you built one. i take the bus. i get off the bus. i don't take a multimeter reading of the fare box and declare it a commit signal. the difference between you and me is that i can walk to the u-bahn without checking my sumif output first.
