As I said, I do use a little bit more water and the number of eggs varies from 3 to 12. Another thing that I do differently is that I put them all together in a small colander, I don't use a rack. Once in a while I quarter a couple potatoes and lay them on top to have for potato salad. They all turned out perfect in just 5 minutes.
I might add that I was a line cook for years and I have cooked thousands of eggs and I never found one to be any different than the one just beside it.
I should add that the freshness of the egg makes a difference when frying or scrambling them, but I haven't found any difference in the way that they cook or peel using the instant pot. They have all been cooked to the same degree and they all peel beautifully.
