This read-only TruthValue tells whether the PoE annual-savings estimate is actually meaningful yet, which requires the device to have accumulated a full previous week of energy-savings data. An admin should check this flag before trusting rlPortStatPOEEstimatedAnnualEnergySaved, since on a recently installed or rebooted switch that has not run a full week, the projection would be unreliable or absent. For example, on a switch installed three days ago, this flag would read false, telling the admin to wait before pulling the PoE annual-savings projection for a report.
