Snagly, never figured out batting averages for catches, nice thought though. May have to try to figure that one out. When guiding for salmon both here and Alaska many clients make wagers on first, most and biggest fish for the day. Rule in my boat is once the guide touches the leader its a counted fish. Cuts out any arguments and kinda makes it fun when clients are screaming at you to reach out and touch the leader, especially when its about 10 feet away. As far as biggest fish for the day, I'm the ref. Definately dont like to net fish to be released or beach them. I'll undoe them by the boat or wade out to my waste on the beach to release them. Once I've touched the leader its counted.
