Weighted On-base Average (wOBA)

How do we know if a batted ball “deserves” to be regarded highly? By using Statcast metrics such as exit velocity and launch angle.
How do you calculate wOBA?
In 2020, the formula for wOBA was (0.699×Unintentional BB + 0.728×HBP + 0.883×singles + 1.238×doubles + 1.558×triples + 1.979×HR) / (AB + BB – Intentional BB + SF + HBP). What's a good wOBA? The formula for wOBA scales it to league average for on-base percentage.
