Peter,
They were both 14" pizzas, but the first one stuck to the peel a little bit so it came out a little ovular. I did count somewhere near 50, but I did weigh the container of pepperoni before and after and came up with 2.9 oz. I have found that overlapping the pepperoni is the way to get the crispy and almost burnt edges that I like. They do shrink down significantly, but as I mentioned earlier, they are much thinner than other kinds I have used. The only thing that bothers me about the oil is that it makes the cheese not brown at all, but as long as I get that crispy pepperoni texture, it's worth it. Even with ~50 slices of pepperoni though, the oil is no where near the level I'd get with 20 slices of the grocery store stuff and yes, it is very nice to not have to waste 3 paper towels just to have edible pizza.
