I have had 3 second hand electric stoves in 15 years. A new one is not in the budget. With each one I have had to adjust my baking temps and times a bit.
I do have an oven thermometer and my current oven is 25 degrees hot. I adjust the dial to be at the right temp.
I have always rotated what ever was in the oven. Even when we had a convection oven that moved the hot air around.
