I just added this small tool to give people a simple way to check the
validity of a benchmark, please use it.

critter# cat chameleon
150
400
720
500
930
critter# cat iguana
50
200
150
400
750
400
150
critter# ./ministat iguana chameleon
x iguana
+ chameleon
+--------------------------------------------------------------------------+
|x       *   x                *       +                  + x              +|
| |__________M___|____A_______________M__|A_______________________|        |
+--------------------------------------------------------------------------+
    N           Min           Max        Median           Avg        Stddev
x   7            50           750           200           300     238.04761
+   5           150           930           500           540     299.08193
No difference proven at 95.0% confidence

Never attribute to malice what can adequately be explained by incompetence.
