If you have a measurement sensitivity of a percent or so, then a factor of 2 is as wide as the sea, and it is clearly enough to rule out one completely and accept the other. This is the *whole point* of quantitative experiment -- to make a measurement with sufficient precision to unambiguously discern which model is right and which model is wrong. You have the completely incorrect impression that, once you get a model within the ballpark, then the rest is just fiddling and fitting. That is wrong, wrong, wrong, and it is not how science works, nor how it should work. PD
