Leaning Tower of Pisa Begins Decade-Long Closure

The Leaning Tower is the freestanding bell tower of a cathedral in Pisa, Italy. Though designed to stand upright, Pisa's most famous landmark began leaning soon after construction began in 1173. In 1964, Italy's government enlisted the aid of a multinational task force to prevent the tower from toppling, but the tilt remained so severe that the tower was closed to the public in 1990. After another decade of stabilization efforts, it was reopened in 2001. What first caused it to lean? More...

Seems like a great deal of effort has been invested in finding out who to blame for the tilt.

Here's my concern:

2001 -- after stabilization the tower is certified stable for 300 years.
2007 -- after further stabilization the tower is certified stable for 200 years.

Extrapolation suggests that this year (2015) the predicted stability will be restated as 100 years.
In 2022 ...

The Tower of Pisa began leaning shortly after its construction. The undersized foundation was improperly laid and the substrate on which that foundation was set down did not properly support it. The ground shifted and the tower began to lean and also to settle, and this was after the foundation was laid and the first three floors were erected. This was before the year 1200, and the tower still stands (but with some help).
