You are right, but my question is... specifically what model or models are being employed? Where do we learn more about this? Obviously, more than a handful of people are concerned. Also, just because a legitimate scientific method is being utilized, does not mean that the models, their interpretation, and selected responses to the findings are correct.
I don't know enough to answer, only pose questions.
You are correct -- whether the method is being applied correctly and whether the interpretation is accurate. What I don't like is dismissing such methods out-of-hand in favor of Joe or Bob's general impression based off what they saw their 3 mornings on the deer stand because Joe and Bob have no idea how such things are done.
What methods are employed in Indiana? I'm not sure. Different departments I've had exposure to use different methods, typically with pretty good reasons for why they chose it. But I do know a retired Indiana conservation officer, I'll see if he knows.
In at least a couple states I know of where similar controversies have stirred, it has nothing to do with the biologists and their methods. The politicians and bureaucrats who actually have the power to make the rules will often just ignore the recommendations of their biologists.
In the area I referenced in Michigan the biologists have said for years that the deer are massively over-populated, yet the decision-makers have not taken appropriate steps. For years they still tightly controlled antlerless permits, and now they mandated a pricey mandatory bundle license which a lot of hunters in the area cannot afford (so they no longer hunt).
