Right now japex only reports/collects the total time taken and the number of rounds and means
calculated. For non-trivial usecases percentiles (e.g. the median) are of interest as well. If one single run
took 91 ms and the other 9 take 1 second, the arithmetric mean will be 10 and the geometric mean 1.
An IMHO easier to understand value would be the 90% value, that is the time in which 90% of the runs did
