Recently new out of box fields were added on the Account table for
Open Deals
Open Deals (Last Updated On)
Open Deals (State)
Open Revenue
Open Revenue (Base)
Open Revenue (Last Updated On)
Open Revenue (State)

To be consistent, these fields should be added to the Contact level as well.

The reason is, an Opportunities can be for Accounts and/or Contacts. If you add new fields related to opportunities for Accounts you need to add the same for Contacts.

If one were to report on Open Deals, the numbers would be WRONG if there are Open Deals that area related to Contacts.
