Help me understand these numbers.

I’ve got a strong student (0 handicap) who’s been fighting an excessively inside path typically around 4–6° in-to-out. Our goal is to get that closer to 2°, which we feel is a better number for consistency. On irons, the path gets really inside (closer to 6°), but with the driver, it actually goes a bit out-to-in, around 2°. So the trend is: the less loft, the less inside the path becomes. Here’s the part I can’t quite figure out: With the driver, the student is consistently hitting a stock draw. Ball starts right and comes back left both on the launch monitor and visually on the range. But with a slightly out-to-in path, that shouldn’t be possible? Another observation: Their hands at impact look quite high, especially with the irons. Could that be skewing the path readings on the launch monitor (i.e., making it appear more inside than it is)? We tried a few fixes, but what actually worked today was focusing on: • Arms shallowing, and • Keeping the chest more over the ball through impact. Covering. As soon as we did that, both driver and iron paths settled into the 1–2° in-to-out range. Very playable numbers and repeatable too. I’m thrilled it worked, but would love to understand why those changes helped the path tighten up. Intuitively, I would’ve expected more shallowing to make the path more inside, not less. Would love any insight.
