That seems to make sense DTES . The bloke definitely had it one time as he showed me the ticket, he said he had the other one only a couple of months before. He wasn't a bullshitter but he was a massive piss artist so he could have got confused I suppose.
Yes, duplicates would be allowed in that 1/3210 so it's wrong.
I know someone who's had this a couple of times before - albeit doing five lines so it's not that unlikely.
