WW designed the points according to a persons current weight. It was designed to keep you satisfied. Naturally someone weighing 350 or more needs more points to begin with.Their points would be 34 daily PLUS 35 flexpoints like everyone gets.
As your weight decreases so do your points.When you reach goal and begin maintenance.points are gradually ADDED back to see how many you can have and remain the same weight.
Hope this helps!
