66g of popcorn (that's two servings, according to the label).
2 minutes and 8 seconds.
After cooking, add oil/butter and popcorn salt, then toss. Popcorn salt likes to fall to the bottom, so after tossing, I put on the popper lid, carefully flip it upside down, and shake.
Also, I use a silicone popper, not a paper bag. (Above, I meant to reply to a different comment.)
I'm eating some right now, turns out. When I'm done, I'll edit this comment with a count of unpopped kernels. :-)
I'm using one called Salbree from Amazon. But looking at the pictures of the other ones, many brands of them look identical, like they're made in the same factory.
