Tom (tcarlson777), this is your thread, and it is a great recommendation for fun, casual remote competition. Since we are using a target designed for a different game, the rules have been discussed since the beginning. Recommendations range from the esoteric to conventional bullseye, best-edge scoring. I believe the decision on scoring format should be yours. The details really make no difference, as long as it's understood and the scoring is consistent among shooters. Using the X dot in some manner is a way to raise the level of difficulty, either a little or a lot. I'll be happy to use your choice of format.
