“Starting this Spring 2020 dart season, we will start using the NADO rating system for registration and team caps. To find your NADO rating please visit: https://www.shafferentertainment.com/nado-rewards/
(Your NADO rating consists of the following formula: Cricket average X 10 added with your 01 average. Example (2.40 X 10) 24 + 22.50 = 46.50 NADO rating.)
Your weekly average will still adjust during the season based on your play results.
