 The Azure usage and billing systems determine your hourly cost by examining your usage for each hour. Usage of all services that you used in the previous hour is reported to the Azure billing systems. However, usage isn't always sent instantly, which makes it difficult to determine which resources should receive the benefit. To compensate, Azure temporarily applies the maximum benefit to all usage received. This may result in Azure applying benefits that are greater than the hourly commitment. Azure then does extra processing to quickly reconcile utilization back down to 100%. Periods of such overutilization are most likely to appear immediately after a usage hour.
