This is true and I know it from experience. Raising the lower threshold 2 degrees made the peak temp the same amount higher. The lower normal temp is like a buffer when the temperature of the room is higher than your tank. The tank's going to gradually get hotter the entire time the lights are on / room heats up. The swing is the same but at least you peak lower if you keep your original lower low temp.
