well, with few exceptions (south sound coho being a glaring one) the ISUs were more accurate than the PSFs in predicting the actual run. But, I am sure you are right about the data. Back in the day of soft data something like 95-99% of all the net catch was in the system three days after the day of landing.

So the reason why we manage on forecasts, and make no changes (like WB and GH) is to save money?

I'll dig out an old quote from a State/Tribal management plan that speaks to management goals.
