James Holzhauer returns to Jeopardy! tonight, following a well-deserved two-week break for the Teacher’s Tournament. We’ve written before about what makes him so dominant—and had Ken Jennings weigh in, as well—but for a quick refresher, it helps to see it in chart form.

No scatter plot can fully capture Holzhauer’s strategic chops; how he starts at the bottom of the board to amass a war chest and hunts down Daily Doubles like a bloodhound. But they can give you a better sense of what rarified space he occupies in the Jeopardy! firmament. All figures are current up to the game that aired May 20.

You can’t win 22 games of Jeopardy! in a row, and rack up $1,691,008 in winnings along the way, without knowing your stuff. Holzhauer takes that to the extreme. Prior to his Monday return, he has given 803 correct responses out of 830 attempts, according to statistics compiled by Jeopardy! enthusiast site The Jeopardy Fan. That puts him second only to Jennings for total correct responses—and Jennings played 87 games.

It’s not just that Holzhauer gets so many questions right. He’s also very rarely wrong, an important distinction to make, since ringing in with an incorrect response in Jeopardy! docks you points. In addition to hitting 97 percent of buzz-ins overall, Holzhauer has correctly answered 49 out of 53 Daily Doubles and whiffed on only one of his 22 Final Jeopardy clues. At this same point in his streak, Jennings was at 94 percent overall but had missed six Daily Doubles and seven Final Jeopardy rounds.

Finding the Daily Doubles is one leg of Holzhauer’s strategy. Knowing the answers is another. The third, and the most important for his eye-popping totals, is his willingness to wager huge sums on them. This next chart shows Holzhauer’s net Daily Double gain from each of his appearances. The numbers vary widely, depending on a few factors: how much money he has at the time, how big a lead he has, and how many of each episode’s three Daily Doubles he finds. But other than an April 26 game, when his opponents beat him to the punch, Holzhauer has bet huge.
