Hey @ShotTakingTime: For tonight's Oreilly race, do you favor team J (J. Alligator, JLo) or team C (Corey, Carson, Creed)?

Hey @EJXD2, I know that you are up late watching Ohio v. Akron football. Do you think that the Zips have a 4th quarter rally in them?

I ❤️ when @horseracing leans into innovation. I am looking forward to Boxing Day to see how "NY or CAN Bred MAIDEN" races are embraced at Belmont. Kudos to @WoodbineTB and @TheNYRA

On this day in 2004, Janet Van Bebber became the only trainer to win a quarterhorse stakes race at a Breeders' Cup host track on the same weekend as the BC itself. Silent Overdrive won the Gr 1 Refrigerator Handicap

Eight months later, my Olympic wish comes true. It's racing on an oval. How can I not watch? @peacock is streaming the ISU #shorttrackworldtour isu-skating.com/en/short-tra…

3 examples for why calibration ≠ accuracy. Accuracy is closeness to the truth. Calibration is interpretation as a valid probability. Neither implies the other. 1. Assign 10% to every horse in a 10 horse race. Perfectly calibrated (exactly 1 horse wins every race), but useless, not accurate. 2. "Yes" happens 90% of the time. Forecast is Uniform 51-100% on Yes, Uniform 0-50% on No. Badly miscalibrated, but useful for prediction (accurate). Beats perfectly calibrated 50/50 forecast. 3. Coin toss that is biased as follows. The side facing up before the toss occurs 60% of time. The side facing up is randomized 50/50. Forecast Method #1 gives 50/50 every toss. Method #2 uses the information and gives 60% on the side facing up. Both are calibrated, Method #2 is more accurate.
These are calibration plots — which says nothing about accuracy. These are nice pictures, but they don’t prove accuracy

Door to Door in 9 minutes. I thought that I gave up being at the track before 6AM when I quit agenting a couple of decades ago

Saturday's Game 1 of @wnba Finals was arguably one of the Top 5 October basketball games in history. The rematch starts in a few on @peacock
