Hi John. At the Red Hawk Lodge, I've been digging into our most recent reserves study, done in late 2020, by Reserve Advisors, an LLC out of Milwaukee. Reading it a few weeks ago, I was really impressed with how comprehensive and well-written it is, so I figured I should respond to your post. KRPM must have found them for the Red Hawk, since they are our PMs. For what it's worth, the author is a licensed reserve analyst, and his name is Nicholas M. Johanning. Their url is www.reserveadvisors.com. Good luck!
