There is a real argument on the other side. Uniform rules are simple, and simple rules are followed.
A differentiated framework introduces judgment at the calibration stage, and judgment is where discipline usually erodes. A single portfolio-wide stop that is actually honored may well outperform a sophisticated framework that is quietly abandoned in the second difficult quarter.
That is a fair objection, and it sets the real test. Differentiation is worth the added complexity only if the rules are written down before entry, calibrated to something observable rather than to conviction, and left alone afterward.
If a framework cannot survive those three conditions, uniformity is the better choice.
The answer to a miscalibrated rule is not to abandon all rules. It is to calibrate them to what each position is actually for, and to how it actually behaves.
