similar to nav

I am a new investor to pre. I have been following this forum for sometime before jumping in. Having looked back at a lot of previous postings, I have seen that pre has been likened as a junior NAV. I also noticed on the nav forum a few names appearing from pre's forum, who seem to post there also.
My question to someone following both camps is this. Does pre have the same potential as nav? In relation to both companies how much bigger is nav? If pre was to hit 'paydirt' in drilling, how much time would it take to get to where nav is at the present time? I read where nav is looking at producing next year, would pre be in this position, if paydirt was hit shortly? Can anyone also tell me, what sort of drill results have nav had from their site that adjoins pre's lease and this common 'shelf' that runs through both leases?
Being a newbie, I am finding it difficult to track down this sort of information.
