Help with Weight Watchers Food Points Calculation

Good evening buddies!

I was wonder if someone with an 'official' Weight Watchers calculator could check my formulas for Points estimations.
I'm not sure if anyone's still got an old Points calculator, but I'd love to get a check on ALL versions of food Points.
So if you have any official calculator handy, please help me check my numbers!

Here's a few set's to check, and the results I am getting with 'un-official' calculations.
Going for big numbers because they will show any discrepancies more accurately.
