It would be nice to show the data in the tables as graphics too, perhaps log-log so it's easier to see all the points.
In the first table:
Benchmark Time CPU Iterations
-------------------------------------------------------------
BM_ListFind/8 2824 ns 2825 ns 247103
[...]
BM_ListFind/8192 3758778 ns 3758624 ns 204
[...]
the last column makes no sense. Is that an error sorting the data or I'm misunderstanding what it mean?
