Boxrec is good. I think I'd go with the Boxrec stat rather than whatever was announced on a 4 or 6 rd preliminary bout between a couple of unknown new pros with a few months of experience as pros.
People will jack up records to make things sound good, and nobody gives a $#!t because they're unknown non-televised local preliminary bouts. Tyson fought in some smokers too way back then, they're not on his record nor should they be.
