A rate file with no reasoning attached is just a picture. Here is what ours carry.
Every zone we flag comes with the index that flagged it, the severity band, the acreage, the product and volume proposed, and an estimated bushel loss if it goes untreated. That last number is the one that decides the order of work.
If a zone cannot carry all five, it does not go in the file. A map you cannot argue with is a map you should not be signing.
