Also I just found this on one of the webpages.
Only about one quarter of people with genital HSV- 1 shed virus at all in the absence of symptoms, while 55% of people with HSV-2 do (Wald, New England Journal of Medicine, 1995). "Shedding data appear to parallel recurrence data, meaning that people who have a lot of recurrences also have a lot of shedding," says Wald.
This implies to say that 55% of people shed the virus, is this information outdated?
