All assuming that you are using the maximum synchronisation speed.
Not sure that comes to play (and you mean minimum, no?). It's far longer
that the discharge time, so why would it matter? As it's not fixed
across cameras, I would expect the flashes to have provisos or sth (or a
calculator parameter).

I meant what I said 8-)
The in-flash quench is done on the amount of light falling on the
sensor. This will give a certain exposure at a certain combination of
ISO, aperture and shutter speed. Generally, the shutter speed is the
fastest which will give a whole frame exposure without banding. This is
generally regarded as the synchronisation speed but slower speeds will
work. Once you start using slower speeds, the ratio between flash-lit
parts of the picture and natural-light-lit parts will start to change.
