only in the group less than 1200 g a significant overestimation of foetal weight could be shown by using the weight curve of the population of bonn , whereas the percentage deviation of both weight curves was comparable : when using the curve of bonn 68 % of readings had a deviation of less than 10 % , whereas with the curve of winterthur this was the case for 65 % of the readings .
