I never saw them in that way. I thought the format was great.
I can understand your thinking on it, though there are differences:
FF, CS: Both used 100 people. FF gave an open ended question, while CS gave you two choices.
PTP: Used 300 people per question (stated by Geoff) and used trivia questions.
I have tinkered with the formats before for GSN games and thought I came up with a nice little compromise. The front game would be the original front game with the jackpot and all (though it was not hit in the three games played). The bonus round looked more like the second main game format with the two players given a choice of two categories for each question. If it was answered correctly, they got the points equal to the wrong percentage (80 points in the second main game = 80 percent wrong) with 200 points winning the bonus (which I arbitrarily set at $20,000....YMMV)
Now the PTP bonus game used was definitely FF influenced. They took the top five answers, converted the replies to percentages to make them total 100%, and inserted a sixth answer and make it zero (PTP's equivalent to the dragon, devil, and lightning.) Getting all five answers gave the player the prize package which included $1000.
