One would learn from experience how to settle on their own flash method. So what if a shutter is open for less time than the flash duration? With as much light as those flashbulbs output one might only need a portion of the flash duration to properly expose a sheet of film. Especially at less than 15 feet away (look at those old photos, prone man 5 feet from the camera, crowd 15 feet away). Then tailor film speed and developing to that normal exposure. Once dialed in it's the same again and again.
