In addition, I think there's faulty reporting in the 1997 article. It says that this model differed from another in the past because it took into account "such potential rewards as the bonus prizes and average bounty available in the Showcase". Well, as opposed to what, stopping and putting sixty cents in your pocket? Isn't it just a matter of winning or not winning?
Also, the article says nothing about what Player Two should do in cases where he's tied Player One. According to the definitive rules as described -- the entire point of the article -- Player Two should spin again at 95 cents if he's tied with Player One ("if the first spin isn't enough to beat Contestant 1").
Of course, the best thing is the paragraph near the end, where these incredibly intelligent men with their sophisticated mathematical models admitted that the contestants on the show were pretty much making the correct intuitive guesses and coming up with success rates near identical to their models all along.
