This is the rate at which an allowance is used up by employees compared to the ideal rate where it is used progressively through the year. It is only useful where a fixed annual leave allowance is allocated to an employee.
The blue line in the chart shows the ideal/target where the amount of annual allowance (not accrual) that has been used up is directly proportional to the time in the leave year. For example, if an employee is entitled to 12 vacation days a year, they would ideally use up 1 day a month.
This can be used to compare employees/teams who use up their allowances too fast/early or too slowly/late.
