Notes
Observations from real systems, written as we encounter them. These entries reflect how we think about system behavior, measurement, and engineering judgment when real-world performance diverges from expectations. They are not announcements or tutorials — just documented thinking grounded in work done in the field.
Recent Notes
Energy Input Is Not the Same as Performance
Why increasing energy consumption does not necessarily indicate improved system output — and how real systems quietly hide declining efficiency.
June 19, 2025What “Normal Operation” Actually Hides
Many systems operate for years without faults or alarms while gradually drifting away from expected behavior.
June 11, 2025Single-Point Pump Selection Is a Lie
Selecting equipment at a single duty point ignores how systems actually operate across ranges and controls.
June 3, 2025Why Measuring Scale Directly Isn’t the Right Question
Some behaviors cannot be measured directly. The key is understanding what must change if the condition exists.
