All I know is that back in the 80s the updates were, with only a couple of exceptions, more accurate than the forecasts.

As to catch, again back in the 80s, more than 95% of the commercial catch was in the computer within 3 days of the fishery. And this was based on summaries from the individual fish tickets.

There were a number of high chum escapements from the mid 80s to 90s. When WDFW ran these through a Ricker Curve MSY model the results were uniformly that the larger escapements produced larger runs, so the goals should have been increased.
