Actually, never. It avoids doing division in order to execute quickly. It only ever compares the cpu usage of the partition, over the last averaging window, with that partition’s budget, expressed as a total time over the last window rather than a percentage. To make comparisons quick, both usage and budgets are treated internally counts of ClockCycles(), not percentages.
