Mathematically if Chameleon rates Dragon last, he comes last overall. It's still too early in the storyline for Chameleon to have a change of heart of sorts in my opinion, so I bet that's what is going to happen.
Bear in mind though that it was mentioned in chapter 7 that this whole training camp is being live-streamed. Basically the magazines most avid readers are watching everything and have probably read all of the entrants task work up until now. Then consider that people were already calling Miyama [Dragon] the "True return of Dragon Land" online. My guess is Miyama pumps out an amazing Chapter 1, but still comes dead last overall due to Chameleon's rating and is blacklisted. At which point there is a large fan backlash online, with people accusing Hanagami Sensei [Chameleon] of being biased against his "successor" Miyama [Dragon]. Then in response the magazine either rescinds the blacklisting claim it was fake to motivate the entrants or a rival publisher snaps Miyama [Dragon] up quickly and we get to add some publishing business level rivalry to the mix.
EDIT: I misread how many points they could gain in this round. There is no way for Miyama to come dead last overall after this round never mind. Most of the rest of my point still stands, but the tension is less.
