I've found I burn the popcorn often with this. Maybe just a lack of experience (we always had an air popper growing up). You can also use small amounts of butter (or I guess oil if you wanted) with the silicone popper or air popper. Having enough oil to cover the base seems like a lot more oil? I could be wrong, just guessing.
There's an element of practice too. Ideally, you want a very thin layer of oil to cover the base, or maybe even less. It doesn't need to be a lot. Also an average saucepan would produce quite a lot popcorn To prevent burning, shaking and occasionally lifting off the hob is required. Also not adding too much corn helps a lot. The maximum a saucepan can take is when the entire base is covered with them.
Eg 1/3 cup kernels, fill same cup halfway (1/6 cup), add flavacol to the oil in the measuring cup & stir, mix with kernels in a saucepan over heat. Love life
