Not in my experience, I usually count 200g per person

That’d be two people, five meals each so a few days. That’s how I usually do it

This is making me chuckle, because I just did this last night for a dinner party. It was a hell of a lot of pasta for 7. I kept it moving, even in my big stock pot. Only a few strands stuck to the bottom. We have leftovers.

I usually cook a quarter of that for the two of us, sometimes half if I want to eat for a couple of days.

2lbs/1 kg is a lot.
