A Fitting Optimizes the Swing You Already Have
Equipment can nudge a ball flight a few yards, tighten dispersion, or fix a mismatch between your body and a stock spec. It won't rewrite a swing path that puts a different result on the ball every time — that's a coaching problem, and a session built on top of it mostly measures noise instead of a real signal.
If your strike is repeatable but the result isn't what you want, that's exactly what a fitting solves. If it's still moving around, we'd rather tell you that up front than sell you a session that won't hold up once your swing changes anyway.
