Here's what SimSights does with a single 7-Iron shot.

Smash factor of 1.28 is below the 1.32 target for a 7-iron — that gap means contact is off-center. At 79.6 mph club speed, a centered strike would bring ball speed from 101.9 up to around 105 mph and add 5–7 yards of carry.

This is the main issue. Your club path is 1.6° to the right — a slight push, nothing to worry about. But your face is 4.8° open at impact, creating a 3.2° face-to-path gap that's well outside the ±2.5° control window. That gap is what's curving the ball and landing you 21 ft right of target. The path is fine; the open face is doing the damage.

Launch angle of 17.2° and spin at 7,140 rpm are both within the optimal windows for a 7-iron at your swing speed. You're getting a 46° landing angle and solid peak height — the trajectory is doing its job. This isn't a launch or spin problem.

Two things: square the face and center the strike. They're likely related — off-center contact and face control issues often share the same root cause. Start with face control: hit half-swing 7-irons focusing on squaring the face through the hitting zone. As the face squares up, you'll likely see the strike center up too, and carry should climb from 139 toward 145+ without swinging any harder.
