How frequently do you need to tune? I usually only tune at the beginning of each season. Does tuning also prolong the longevity of the board? This article doesn’t seem to address that.
Filing edges and base grinding cuts material away so it shortens the life. Not a huge concern though.
Racers typically wax and tune edges every 10-20 runs.
Recreationally, if you are on a narrow groomer type ski on icy runs, every few days is great and will help you enjoy and improve faster. Well fitted ski boots are more critical though.
