PHY.1:9 - Consequences

The construction can reveal an impossible experiment before equipment is built. It can also identify useful freedom: a different load, medium, time scale or restricted output may supply the answer with less work. A failed similarity condition becomes a physical design question rather than an unexplained disagreement between experiments.

The price is making the physical premises and coupled settings explicit. A complex account can require several comparisons or a numerical analysis. The method can reduce that work by selecting a sufficient output, but it cannot supply a missing physical law from dimensional consistency alone.
