I wonder if educators have trouble making the trade-off between "Do I spend a little effort to make sure the just-good-enough kids stay clear above that good-enough line? Or do I spend a lot of effort to bring almost-good-enough kids above that line?" If girls have a head start at 5 years old, there may be a compounding effect. It is sad to think about. I guess if you can afford private schooling and tutoring, you can decide how to allocate those resources. In public school you're a little bit at the mercy of your zipcode.
