These kinds of responses aren't helpful. Your response essentially muddies the water because it sets an artificial standard that nobody can/will meet. Yes, you're correct. There likely is some grey area with how we decide to give credit. Are we talking about the same story? This isn't "a polynomial". This is a research program that has been ongoing for years or possibly decades with nontrivial contributions. If you're not sure what does or does not deserve credit, you should engage with the community instead of suggesting that the idea of giving credit is "vague".
