How Often Does The S&P 500 Return Over 32%?

I came across an interesting blog which discusses how many times the S&P 500 returned over 32% in a calendar year.  I was surprised by the result and I am sure you will be too.  Does this further support index investing?  Does earning alpha really matter?  Are you in the camp that what matters is your personal inflation rate or spending habits versus your income?
