Add a column for a Reserved Instance's normalized units. When trying to account for the consumed units related to a reservation ID, the quantities should add up to the total normalized units reserved by that RI. The way it is currently set up can make the consumed quantities appear to be larger than the reserved quantities because the factoring/scaling is different between multiple instances sizes in the same family.
Consumed quantities can also seem lower than reported because of delay in sync with information in reservation portal blade.
We added RINormalization ratio to the usage data for EA. Please check: https://docs.microsoft.com/en-us/azure/billing/billing-understand-reserved-instance-usage-ea#reservation-charges-in-azure-usage-data
Ack on the feature ask. We are working on ways to make the usage data easier to understand and normalized hours is definitely a needed item.
