For available water, I would recommend researchin pwp (permanent wilt point). That will provide a good deal of clarity.
You are not going to find any type of chart that tells you what to set it to,because many things go into it. If you have a warm season ryzome, you can lower it from the default, I'm currently at .1 (tif 419) to encourage deeper roots. so this means that the last .1 inches of my root zone will no longer supply enough water to transpire and the plant will transpire all of the water in leaves until they dry out. Once that process begins, it is irreversible hence the name. But with most grasses, the root system will burn starches to make a growth run to reach water. Some call this training.
If, I understand it correctly from my own reading.
