@quantumcowboy Yeah. Living in California, I’ve often wondered the same thing about low-flow faucets and shower heads: at some point the flow becomes *so* low that people have to spend more time using them just to rinse off the soap.
I’m sure someone’s done the math to optimize water use in real-world scenarios, but judging by a lot of restroom sinks, I don’t think the market has taken it into account.
