You mean 5 times the minimum of 1.5 km for special VFR?
Special VFR only applies within a Control Zone and is subject to ATC clearance.
Anyway, minimum visibility is 5 km below 10000 feet. If they were reporting 5 statute miles, which is 8 km, it's 1.6 times the minimum. BTW, 8 km is the minimum above 10000 feet.
This comes to show how low the legal minima are. 8 km visibility is not much at all, certainly a big stressor for the VFR pilot if he's flying in unfamiliar territory.
I still consider a widespread visibility of 8 km as marginal for VFR flight.
