Moto3 World Championship leader Jack Miller would give himself a mark of just five out of ten for the season so far.
“Because even though we have four wins and are currently Moto3 World Championship leaders, there are some races where I have made big mistakes - which we cannot afford if we want to fight for the title,” said the Australian teenager.
Without a podium during two seasons on Honda machinery, Miller achieved instant success with victory on his Red Bull KTM Ajo debut in Qatar.
"I was hoping to win a race or get on the podium [this season], but winning the first race in Qatar was something really nice,” he said. “My first podium and it was a win! To lead the World Championship after nine races is a great joy.
"Although at the last race in Germany I enjoyed myself a lot and had a well-rounded weekend, I'll take the win Le Mans [as my best] over that, because it was different. It was a race in which there was continuous overtaking - no respite. When you cross the finish line in first position after a race like that, you feel even better than normal."
Miller leads the championship by 19-points over Honda's Alex Marquez despite failing to finish two events due to mistakes in Italy - while battling on the final lap - and Assen, when he fell while leading early in the race.
"Without a doubt, Mugello [was my worst race]. At Assen we were doing very well all weekend. Even in the race it was possible that we could have had one of our best grands prix, as we got pole position. In contrast, at Mugello we suffered a little in the race and ended up crashing."
One of Miller's key attributes this season has been his late braking ability, although he was reluctant to call it his main strength.
"Possibly yes, but it is not for me to say. I also do very well when cornering. In these Moto3 battles to the limit, whoever brakes latest has a lot of the hard work done. I think it's something I've learned over recent years in Moto3. Motocross and dirt track have also helped me with this."
Looking ahead to the second half of the season, the 19-year-old is determined to dial-out the mistakes.
"I should be going for the win at every race, because we have the potential, but we must be smart and think about the overall standings as well. We cannot make the same mistakes. I'm here to try to win the Moto3 World Championship."
Miller added: "I'm sure Fenati, Rins and Marquez will be there, and maybe some more riders too. Of course, I hope to be part of the fight as well."
The Australian believes the championship battle will go right down to the Valencia finale, while in terms of individual races he is naturally looking forward to his home round at Phillip Island in October. Victory in front of the Australian fans is sure to see the colourful Miller put on an impressive range of celebrations.
"I don't usually prepare my celebrations. It depends on the moment and how hyped up I am. I guess I'd go a little crazy, but that's nothing out of the ordinary [laughs]!"
During the interview, conducted by the Red Bull KTM team, Miller did not comment on rumours that he could move to MotoGP next season.
