The "My Bag" section of the Garmin Golf app allows to specify the club type, shaft flex, shaft length, and the nickname for the club. The average and max distances cannot be edited or user entered, as those require distances recorded from actual rounds of golf where the club prompt feature is used to assign the club to shots detected...or by using the Approach CT-10 sensors paired to the watch assigned to the clubs to automate shot tracking.
If you have max or average distances that needed corrected, the scorecard where the shot was recorded too long, or short must be edited to correct the data...which will result in the max and average distances from accumulated scorecards to accurate reflect actual distances recorded during your rounds.
If using the Approach R10, the distances for average and max do not calculate due the sessions being simulated. Garmin golf products that use GPS and support shot detection features must be used and recorded through a scorecard on an actual golf course.
