There is this: https://en.wikipedia.org/wiki/Variability_hypothesis

And I think some mathematician demonstrated that this variation was
evolutionarily optional (I think because a male can have many more
offspring than a female in her lifetime). So if there is a choice in one
sex displaying more variability to select for, adaptation can occur faster
when that variability is in the male gender.

This also necessitates the statistic you pointed out: for this to work some
males need to have more than their share of the children.
