I have rescored the problem after adding more robust test suites.

I don't understand why the checker is rounding the answers, nor why some implementers are rounding the answers. Maybe it's to avoid roundoff issues, which admittedly are an issue when testing equivalence, but any reasonable solution to the problem should be able to give an answer out to 5 or 6 decimal places.
