This pseudo-benchmark is an aggregate statistic that
shows the geometric mean for all benchmarks.
Where other benchmarks display timings in seconds,
the numerical scores for the geometric mean show the
(geometric) average ratio of the system's time to
the fastest system's time.
An average ratio of 1.0 is the lowest possible, and
can be achieved only by a system that is fastest on
every benchmark.

The R7RS (small) standard does not require implementations
to provide all of the R7RS standard libraries, and some
implementations are unable to run some of the benchmarks
for other reasons as well; furthermore, our benchmarking
script gives up on any benchmark that takes more than an
hour to run.
The geometric means for each system were calculated using
only the benchmarks that returned correct results in less
than an hour.
When implementations of the R7RS are more mature, the
geometric means will be recalculated to impose a penalty
for each benchmark an implementation is unable to run.
