You can start recording performance stats, and scorecards fresh without having to clear any of your data.
If you access your scorecards through your account, you can toggle the "Exclude from performance stats" switch to prevent your scorecards from being attributed to handicap, shot distances, or distances attributed to clubs from scorecards.
Then retire your clubs in the "My Bag" menu and create a new set to sync over to your Approach S42 and you can begin tracking distances going forward from that point.
