How to read this. Each cell is percent weed control, averaged across the universities selected above. Hover a cell to see how many sources rated it and their range. A pass with a tank mix takes the best product in that pass for each weed.
Best pass shows the single strongest pass for each weed, which is the conservative view. Layered treats passes as independent (1 − product of misses), so it assumes a PRE and a POST add up; real fields usually land between the two.
Effective SOAs counts the sites of action in the program from products rated 85% or better on that weed. Weeds controlled by only one effective site of action are flagged, since that's where resistance develops.
