What McJared said

p-value bro
Post up the top 3 or 5 or 7 whatever trout 'waits' for each year. You can easily plug that into MS Excel and get a graph and figure out if those weights are statistically significant. MathGeek can probably do it in his head

This would actually be something worth doing. Post em up and see what we can figger out.
I would bet its not statistically significant with a p-value set at 0.05.
I saw you have the waits in another thread, i will try and run the numbers in a bit
