When using 115V main the bottom of the ripple is going to be about 12.5V which is a little less than whats necessary for regulation. Yes the voltage will be a little higher due to less than max current draw, but not by all that much, these transformers actually have pretty good regulation characteristics. If you can guarantee to be running at 120V at all times then it would probably work fine. I'm just trying to give enough margine so that at worst case conditions (high current draw and low mains voltage) it will still be in regulation.
