Supermacro doesn't fire the flash, so I've never tried the lens in SuperMacro, or in fact even used SuperMacro underwater at all. Maybe with the greater amounts of ambient light at snorkeling depths, you could manage a SuperMacro shot without any flash, so at worst you could try it to see what happens.
And about the distance... I dunno, I'm always looking at the LCD to try to get the shot the way I want it, not measuring the distance to the subject, but if pressed to guess, I'd say a couple of inches.
I believe you're overthinking this. Equipment can only do so much...most of the magic comes from the power of the operator behind the lens, not from the optics.
