Did that change actually help?

You changed your diff preload, your wing, your pressures — and the lap time barely moved. But lap time hides the truth: track evolution, traffic, and your own inconsistency all muddy it. The Setup Change Report measures what you actually changed, what we expected it to do, and what really happened.

• Isolates the effect of the change from the noise of a normal session.
• Tells you whether the adjustment helped, hurt, or did nothing — with evidence, not vibes.
• Stops you chasing a setup direction that was quietly making you slower.
