Had a weird moment last month on a job in Boise where I finally understood why my old foreman was so picky about mixing times.

Doubt it makes that big a difference honestly (seen plenty of rushed jobs turn out fine).

My uncle was a concrete contractor for thirty years. He always said the difference between a good slab and a cracked one is often just ninety seconds of extra mixing. I saw it myself helping him once, two identical pours from the same truck, but the second batch got rushed. The finish was chalky and it didn't cure right. That pickiness isn't about being difficult, it's about the material needing that full time to come together.

Watch a cake batter get pulled out of the mixer too early and you see the same thing. The crumb is weak and it sinks in the middle. People rush things that need time to settle and combine. A few extra minutes of mixing or waiting or whatever makes the difference between something that holds up and something that falls apart later.
