As you noted, the number of segments may need to be recalculated. The segmented donut from the Education Development Trust has a fatal flaw: The the chart doesn't show the data. It shows 22 of 24 segments in orange. 22/24 is 91.67%, not 96%. If they wanted to round the numbers to only show complete segments they should have used 23 of 24 segments. That would have been 95.83% Better would have been to show 23 and a little sliver to show the remaining 0.04.
