So, at +1 over ambient light the distance will be shorter. You see the EV dial is changing the ratio to ambient, not supercharging the total output. You use the EV dial to adjust the look of the shot. At -1 or -2 the flash will fill the shadows but not look like a flash shot. You would use the plus side for several effects. At weddings the bride is usually in white so you need to force more flash to keep the dress white. Another use of the plus side is to make the subject POP. This technique is done by underexposing the ambient by one stop or so depending on film stock. Usually done by changing the EI setting or on a manual camera setting the aperture smaller. You then adjust your flash to put out more light relative to ambient with a minimum of the same on the plus side as the ambient is negative. Most people on negative film would add at least a half stop more. When printed, the main image is right and the background is darker but not obviously darker as in a P/S at night. In practical terms, say you are using a 400 speed film. Set your EI at 200, set your flash a +1.5, and shoot away. This is a great method of separating foreground/background in busy settings.
