Maybe a 100 years ago. With today's fundamental physics experiments (accelerators, non EM telescopes, and especially quantum foundations tests) the mathematical constructs are an inseparable part of the interpretation of the experiment. And there it is hardly over fitting when the same results come from vastly different mathematical constructs.
