VTA for Discovery cartridge

I've just mounted my Clearaudio "Discover" cart. When I read the spec, I realise that it says there's a white line on the side of the cart that's supposed to be perpendicular to the record surfact for correct VTA. However, it will mean a highly negative VTA. By highly I mean so apparent you can see the tail dropping even 10 fts away at the listening position. I doubt if this is the case? Any Discovery users care to share?
