Hi Mike,

Thanks for a quick reply. Maybe its my warped mind that had me consider 
that the management of timeouts (sliding the timeout up and down - as it 
appears in the logs) would affect the distribution of timeouts and 
therefore the pareto distribution around them.

I will admit to experimenting with smaller values of 
CBT_DEFAULT_QUANTILE_CUTOFF. These lead to 'peaks' in the timeout 
distribution. The smaller the value, the tighter these 'peaks' seem to be.
    

This should not be the case in 0.2.2.14 and above. Changing the
QUANTILE_CUTOFF default should now only govern which circuits you
actually use. Circuits should continue to build until
CBT_DEFAULT_CLOSE_QUANTILE, so the distribution of recorded buildtimes
will be much more insenitive to changes in the timeout value.
