I believe that the escapement goal is 350,000 fish. That is supposed to encompass all of the tributaries and the in-lake spawners as well as the Cedar river fish. I'm sure that WDFW and the tribes didn't pick the number arbitrarily, it was negotiated by biologists from both entities. I believe that if you look around on the WDFW site, there is some info as to how the escapement number was reached.
