The share of a shipper's loads on a lane tendered to the broker first, from the routing guide where shared or inferred from tender timing. A backup position that accepts nearly everything it sees, on time, is the case for primary; a primary position that rejects is a lane about to be lost.
Fifty loads a month as third in the guide are the loads two others refused.
Broker's acceptance and on-time, and the incumbent's rejection rate from the shipper's own data.
Tenders received as the first offer divided by tenders received, by shipper and lane, from the tender log's sequence or the routing guide.
On a shipper's tenders the broker was first call on 40 percent and second or third on 60. Backup freight is irregular and harder to cover.
Being on the routing guide counted as winning the lane.
