Reading this record

What is comparable here?

The cost database does not identify each contract’s specification edition or special provisions. No edition is inferred from the bid-opening year. These source observations are available for review but are not benchmark eligible.

First we take the median of eligible bids within each contract, then the median and type-7 P25/P75 of those contract values. Contracts have equal weight regardless of bidder count. Extremes are flagged, not discarded for price alone.
