@jleh I get to the info. from a slightly different path, which allows you to pick the depth that you’re looking for and it returns a weighted average. I think the table from your post above lists the data based on the assumption of 60 inches of depth, which is why you end up dividing the number in that table by 60 (to get it ‘per inch’). I would think the most accurate method would be to choose the depth of your deepest roots in that zone, but I’m not positive on that. Since my AWC doesn’t change much with depth it’s of less consequence to me.
To see how I get to this part of the WSS website see this post: Moving from flex monthly to flex daily
Here’s an example of how my AWC changes from 0.12 to 0.13 when I change my depth from 20 inches to 60 inches.
