Rivrguy,

From what you posted above, it looks like the "new" tool is QIN coho CPUE during specific statistical weeks. Call me skeptical, but there is generally too much variability in small fisheries - and all of GH combined is small these days - for any correlation to be very accurate or consistently accurate. We used to do this all the time on the larger Skagit and get R-squared values like 0.5, 0.6, when any value less than 0.9 is statistically weak. WDFW can use this tool, and they will get a number, but that doesn't mean the number will even be close to accurate.
