Counting 2008 the Trib has owned the Cubs for 27 years and made it to the playoffs 6 times (1984, 1989, 1998, 2003, 2007, and 2008). If I'm doing the math correctly that's not even remotely close to "10% or less of the time." I was going to say that you have to win a game in the playoffs for the appearance to count, but they still squeak by even then.
