There are many questions on Meta with people essentially saying "I don't have an acceptable answer to several challenging questions and therefore my Accept Rate is low." Several comments indicate that anything over 70% is fine and that we should not worry so long as our Accept Rate is above that threshold.
The problem is that we're all sensitive to numbers and 70% is less than 80% and 80% is less than 100%. If being above 70% is all we should be worrying about then why don't we get rid of the number and give a color grade of Green/Yellow/Red to indicate the Accept Rate?
The green indicator would symbolize that the poster accepts an, ahem, acceptable number of answers. I would prefer to not accept certain answers but getting below 70% is what is concerning me. That is bad behavior. I should be worried about the answer. If I'm green then I can relax.
A yellow indicator symbolizes that improvement is needed and red symbolizes a poor Accept Rate.
We want people to be actively testing answers and accepting the best answers. Instead, the current system encourages people to worry about the Accept Rate and not the best answer.
