Quoted from Pedleboy:
He is impressive but Ken's 74 day is much, much harder than pressing the money. We've had this conversation many times in my office. I watch Jeopardy, on average, 4 days a week and it's funny to talk to people who just watch guys like James play. They think that he is some super human that has developed this whole strategy. The reality is that all 3 players know the answer to 75 to 80 percent of the questions. Jeopardy is all about clicker control. James is very good at it as was Ken.
While I don't disagree with you about James' clicker control/timing being excellent (and imperative if you want to crush the competition); however, I think you're downplaying how many questions are actually answered correctly per "normal" show, and what the contestants really know. Traditional difficulty shows a 2 to 1 ratio of correct to wrong answers. So in reality, it's really more like 67%, than 75% to 80%. There was one season (season eight) that had a 4 to 1 ratio. Otherwise, it's typically 2 to 1.
To compare that to James, he's getting 97.31% of his buzz-in answer correct through his first 25 games compared to Ken's first 25 games at 92.49%. With the random categories you could receive in each game, that's beyond impressive.
On top of that, him "pressing" or risking 5-figure amounts with consistency on Double and Final Jeopardy is unprecedented on the show. James' average risk on Final Jeopardy is $28,720 compared to Jennings' $6,686 (through their first 25 games). People are scared and nervous to risk large amounts of money. The money amounts are grabbing everyone's attention.
In my opinion, you have to give James a lot more credit than just being fast on the clicker.
