The falloff never came, 23XI put all four cars in the top eight, and the single-lap board is lying about two contenders. Every file from the first Cup practice at Chicagoland since 2019.
Intercepted Audio “ ” Fifty minutes, three sets of tires, seven years of dust — and the falloff everyone planned for never showed up. 23XI put all four cars in the top eight, the single-lap board is lying about two contenders, and our Best Bet spent the day in the garage. Chicagoland Speedway · eero 400 · Sunday, July 5, 2026 · 6:00 PM ET · TNT · By PitByNumbers Staff One caveat the booth flagged before anyone gets carried away: the O’Reilly Series was rained out, so Cup cars were the first thing on this surface — meaning Friday’s rubber-free track wore tires HARDER than Sunday’s will.
If the falloff looked mild on a green track, it’ll be milder still in the race. Track position and clean air just got even more expensive. The board itself needs a decoder ring.
The fastest lap of the day belongs to a driver whose long-run sheet ranks in the teens. Two of the slowest headline numbers in the field belong to cars with top-five race pace. And the best five-lap average of the entire session belongs to the one name nobody had in that sentence — a Ford, on the bubble, one point out of the playoffs.
Here’s the full chart, then the files. Full context: our top-10 card and the odds board are both live for Sunday. The one-lap board says Herbst.
The race says Reddick, Larson, Wallace, Hamlin — and watch the two liars: Blaney’s P22 hides the longest run in the field, and Byron’s P16 hides the smallest drop-off on the board. Cindric just made the bubble a live wire, Jones’s Best Bet case now rides on a repaired floor, and qualifying goes Saturday at 3 PM ET with zero warm-up laps — first flying lap of the weekend, on the clock. Friday told us the tire is tamer than advertised.
Saturday tells us who was listening.
