If I haven't already shared it with you, just let me know, because I created, imho, a really detailed customized report, which references all of the haag and Insurance Information Institute documents, along with remarks about granule loss from several manufacturers, which more clearly identify what is and what is not hail.
The small hail guide booklette that the insurance adjusters are given from the Property Research Bureau as a guideline to follow is an edited version of the original haag documents, which intentionally mislead and misguide even a reputable honest adjuster, if they only go by that book.
On the front interior page of the booklette, it even states that the original intent of the cited authors and papers may not accurately convey thier intent and meaning.
