A couple of "Filling Foods" questions

As I mentioned, I recently tried the free online WW trial and have a
current copy of the "Filling Foods" list and the current "Momentum"
plan and its "Simply Filling" variation.

I have two questions about this:

(1) Comparing Simply FIlling to the old "Core" plan I cannot see any
difference at all - not in the foods list, not in the free weekly
points allowance, not in activity points, not in the suggestions about
portions or listening to your hunger signals and avoid overstuffing.
Are there really any differences at all from Core?

(2) How do foods which are made from Filling Foods and non-Filling
Foods work again? For example, if I make a stew from Filling Foods and
add a non-Filling Food ingredient to it, do I just count the points of
the extra items against my weekly extra allowance?

Thanks,
