This does not surprise me, as the courts are flagrantly biased toward women in these matters. Almost without exception, they come out ahead in every measurable metric.
This is not always exactly true if you dig into the details - for example, something like 20% of fathers get custody - but it's something like 90% of fathers who try to get custody get some.
How many don't even try though because them assume it is hopeless. Some custody includes things like 1 weekend a month - if that is all you get it wasn't really worth the bother.
