"WebUse ignore_bins: If you use the ignore_bins construct for large values, then it will ignore unnecessary large values, also helping you avoid fatal errors. Problem-2: The coverage calculation for a cover point generally does not take into account the coverage captured by the default bin, which is also excluded from cross coverage.
