I see where she's coming from. When it was played to 25, you had to pay attention to the clues pitched and remember what was said, then put 2+2 together.
Although P+/Super Password reduced the number of guesses, you now had to pay attention to the clues, then remember the words for the puzzle. I enjoyed both versions, but I could see how that may have confused the old-school celebrities, especially ones like Elizabeth who guest starred early in the run.
I believe Chris C. may have mentioned it, but whose idea was it to do a puzzle and what was the reasoning? Was it just the consensus that the CBS and ABC methods were considered too "boring" for 1979 TV?
