The records are only reinstated in Guinness, not in TG. Like him or hate him Billy is a legit player and he can put up those scores. No one can argue Pacman. And we know Billy has broke 1 mil on DK. There are better DK players that point press harder than Billy. There are only a handful of players that can crack 1 mil on DK period.
I believe a new DK WR was set this week by Robbie Lakeman. He scored over 1,260,000. This is probably about as high a score as we will ever see. Theoretically it is possible to achieve 1.3 or even 1.5 million.
