--- Comment #3 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
I ran Speedometer with some instrumentation. The max number of entries in the vector is 25, and the mean is 1.63.

Here's a table of size frequencies (excluding zeros):

Size  Instance count
 1     25751 
 2      3388  
 6      2010  
 3      2010  
 4      1020  
 5        50  
 25       20  
 9        18  
 17        8
