Statistics reports with seType=Sectors shows percentage without decimal point. In case the number is less than 0.5% it is shown as 0%. The error becomes considerable for large data.
Please refer the screenshot below, it shows Windows 8.1 0%, while the actual number is 12. This is misleading for an user and a decision based on it will be wrong.
It must be enhanced to show at least one decimal point, if not two.
