The endpoint of an aquifer test is rarely the parameter itself. The endpoint is a decision:

  • how much can be pumped;
  • how long pumping can continue;
  • how much residual head is acceptable;
  • how wide the safety margin should be;
  • whether recovery will be fast enough.

Transformation uncertainty becomes useful when it reaches that endpoint. Otherwise it remains a methodological concern with unclear practical force.

The operating rule for future papers is therefore strict: a new interpretation framework should show where a flux-gradient mismatch, model pathway, or fitted difference changes a decision, not only where it changes a curve.
