That is actually a dumbbell press rather than a CDB press. The CDB is a whole other animal, because the bell diameter prevents you from getting a very stable position in the rack, which makes leg drive difficult to translate.
@brady888 can talk to his experience at his last show with the difference between the two. His write up was spot on.
You could try to replicate it using larger diameter plates, or try the home depot bucket bell idea I posted here
For weight in a show, I have seen everywhere from 100 to 125 for local shows in the 200lb class.
