The diary entry
March 17, 1986... It's a hollow victory that comes at someone else's expense. If I'd won, I still would've lost.
is different than the original diary entry. There are three differences. First the date "March 17, 1986" does not agree with the original entry, which has a date of "April 14, 1990." Second, the punctuation and spacing are different. Finally, this new entry has a different ending sentence.
The original entry is from the season 1, episode 23 episode titled "And the Winner is..." aired on March 28, 1990. It reads:
APRIL 14, 1990... It's a hollow victory that comes at someone else's expense... I wish I'd understood that a week ago.
