You now know what needs to change. The Feeding schedule translates that into when and how much — per feeding, at the barn.
Without a schedule you keep calculating yourself how to spread the advice over the day. That costs time, and a mistake easily creeps in.
Adjusted the ration? Recheck shows whether it has really been corrected — instead of hoping it's right.
Without a recheck you never know for sure whether an adjustment worked, or whether you've quietly drifted off again.
