id say, if someone runs 3 or 5, he could as well also post all.
One simply feels more confident when seeing all. For example when all 3 of
group A are lower than all 3 of group B then this gives more confidence
in A being faster than if for example 1 of A is faster than all of B
while 2 of A are slower than all of B ...
