I came across this article in Golf WRX about how dynamic loft and AoA factor into launch angle. The important parts are as follows:
Factor in the following numbers for this shot:
Launch Angle: 11.9 degrees
Dynamic Loft: 13.5 degrees
Angle of Attack: 2.8 degrees
Understanding that dynamic loft is 85 percent of your ball’s launch angle and angle of attack is 15 percent of your ball’s launch angle, we now see that the dynamic loft of this shot hit was a touch too low.
Dynamic Loft: 85 percent of 13.5 degrees is 11.47 degrees.
Angle of Attack: 15 percent of 2.8 degrees is 0.42 degrees.
Add those numbers up and you get 11.89 degrees for your launch angle.
At my Golftec the launch monitors only measure LA and not DL or AoA. For those of you who are better at math than I am, could I somehow reverse engineer what the Golf WRX article says using only the LA to parse out AoA?
