Dammit, I know the answer to this, and it's written on a small scrap of paper somewhere around here. I also told Marco, so she may actually remember the number.
I'm thinking (almost, but not quite guessing), that I got 4 oz of seed per sunflower. And that the shelled weight was 25%.
I remember a bunch of dividing by 4 when I did those measurements/calculations.
I will look. I need a real notebook, instead of scraps of paper that I do calculations on.

I looked in your email to me and mine to you looking for the number of sunflower seeds you get from one sunflower. Let me look one more place to see if I can find that.
