Do Not Spray Your Piece Until right before adding egg.
Let it reach medium (you will know you are at medium because if you splatter water on piece the water will turn into balls and roll around. if water just splats it's not hot enough yet.)
Once your piece is at medium, then and only then, do you spray (make sure you cover the entire area you will be adding eggs).
Drop your eggs and immediately turn to low.
1 min / side for over easy. 2 min for over-medium. 3 min /side for over hard.
