I partially agree with your comment, the math is fuzzy, and I'd say that saving 5 minutes per day is absolutely worthless, I don't care about that time, it's a rounding error. There's a cliff when doing this kind of math.
But I prefer to invert this thought experiment - my time isn't worth $x because I intend to use that time for something I can invoice, it's the amount you'd _have_ to pay for my time in order to incentivize me not to spend it walking around the park, watching a movie or whatever but rather do some marketable work.
So yes, I kind of know the value of my time, I'm willing to pay $x not to be bothered with some things, e.g. a washing machine. I don't care about spending +10 minutes when buying some item.
