Cull from the size group that is over the limits set by Anderson (crowded group) first and take out all that seem in less than ideal condition. Then cull a few from the other class sizes and make all of those be fish in poor condition. I can use the eyeball test to pick them out. With a little experience the eyeball test is close to what RW will show.

I would shoot for 20 lbs per acre while watching RW and condition to adjust that number.
