Laundry

ADDENDUM

Since conducting this study in June 2024, I have continued collecting and analyzing data from the London House laundry room.  I can now expand on the results presented above, to provide a slightly more accurate view of the laundry timings across various seasons.  As hypothesized, there seems to be an obvious correspondence between time of year (i.e., temperature) and washing duration, illustrated by this beautiful sinusoidal curve tracking washing times from 17 December 2024 to 17 December 2025. 

Additionally, when including more summer months in the study (i.e., data from December 2023 to January 2025), the mean washing time was found to be 44:40 (mm:ss) ± 04:23, and the mean drying time was found to be 60:19 ± 00:49 (n = 47 washing, 42 drying); this is illustrated in the adjacent figure.  The slightly shorter washing time and relatively unchanged drying time from the above study may reflect the effect of outside temperature on the time it takes to heat water during a washing cycle.

Unfortunately, at the start of February 2025, Circuit Laundry abolished the Circuit Laundry Plus system and replaced it with the Circuit Laundry Go system, at least insofar as Goodenough College was concerned.  One can only guess at the next miraculous name of whatever forthcoming Circuit Laundry app is in the works as a daring attempt to correct the incapacity of the prior model(s).  It can be said, however, that the timing of the Circuit Laundry Go system is astonishingly consistent: from February 2025 to July 2025, I found a mean washing time of 39:55 ± 01:19, and a mean drying time of 60:03 ± 00:14 (n = 24 W, 19 D).  The graphic representation of this is quite boring, as shown adjacent, and consequently the only remaining remark is the indeed astonishing knowledge that the timing of washing machines could have been so precise from the beginning—that is to say, it was apparently possible all along.

It also means I have no more analysis to do.
