I add maybe a half a cup at the beginning just to help get a rolling boil

If you add salt to water, you raise the water's boiling point, or the temperature at which it will boil. The temperature needed to boil will increase about 0.5 C for every 58 grams of dissolved salt per kilogram of water. This is an example of boiling point elevation, and it is not exclusive to water.
