Chris,
Here is a study from 1986, while not recent is certainly more current that
Friedman. Bottom line is a finding that most (90%) of women who went on to
vaginal birth dilated at greater than1cm/hr after reaching 5 cm of dilation.

Subject: length of labour
dear all
I'm interested to know whether there is any written or research evidence
on whether norms of the length of labour have changed in the recent
past. I'm aware of the impact of Friedmans work on practices in labour
wards, but am wondering whether there is anything to suggest further
trends in what is seen as a 'normal' length of labour (and by
association, whether this could be related, in either direction, to
rising intervention rates)
all ideas on relevant evidence sources, or personal/professional
observations welcome
Chris
