Hi monty. General thought is yes, use them all. They drop at each stone until minimum 29. Some don't use all the weekly pp and most don't seem to use activity points. I use all daily and weekly pp. Haven't done much about getting active yet, but I will need to soon to tone up!! WW see the pp programme as more of a lifestyle change than a diet, this way we're more likely to lose gradually but also to keep weight off long term.
Good luck!!
