Abstract
We verify an upper bound of Pach and Tóth from 1997 on the midrange crossing constant. Details of their upper bound have not been available. Our verification is different from their method and hinges on a result of Moon from 1965. As Moon’s result is optimal, we raise the question whether the midrange crossing constant is .
