A summary of 100 EXPLAIN timings looks like this:

min        0.10       0.10       0.30       0.29       0.66       0.23
max        1.07       1.00       2.13       1.98       4.52       1.59
median     0.49       0.52       0.31       0.33       0.68       1.12
average    0.43       0.35       0.62       0.49       1.01       0.89

What are these? Times? in ms?
 
However that was the idea of the benchmark, and I got no difference.

Please explain what this means and your conclusion, so its clear. That way we can either reject the patch or commit it. Thanks
