Here's a fun fact.
https://en.wikipedia.org/wiki/VANOC
"On January 30, 2009, VANOC announced its updated budget for the 2010 games. The operating budget was set at CAN$1.76 billion, with a contingency of $77 million.[5] This reflected an increase of $130 million over the $1.63 billion operating budget announced in May 2007..."
Initial stated budget for Vancouver:
$1.76 billion
Final cost for Vancouver:
over $7 billion (

Change: 398%
Initial stated budget for Calgary:
$5.11 billion (

Applying that change rate, the Calgary Olympics would cost $20.3 billion. That's obviously not and hard-and-fast way of looking at things but it's a damning indicator against a "model Olympics."
