THE TRUTH ABOUT ESPRESSO: Understanding Espresso Flow

I take a deep dive on profiling espresso and look at terms like water debit and puck resistance. If you enjoy learning about or drinking espresso, I suggest you watch! NOTE- The Decent Espresso Machine is not 100% on knowing input flow. It estimates the flow based off a complex algorithm. Supposedly, it has a 20% bias, which is quite impressive. ANOTHER NOTE- Parts of the video sound like I am saying water debit is a constant throughout the duration of the shot. Please know that is NOT what I mean. The OPV not only shunts flow to bring pressure down, but the pump itself lowers the flow rate once pressure rises, hence my equating espresso flow with input flow.
