To me it was 9.75. Nascar's low downforce era continues to provide a scintillating degree of difficulty on fast intermediate tracks, with the drivers having to apply effort and skill to maintain competitive speed. Clean air will always be a benefit, but today they could (and did) run close, run side-by-side, and execute passes. This race was a cliff-hanger to the very end, and great to see Larson break his duck, with Elliott and Blaney in hot pursuit.
