Stoner is 'refusing to make predictions' over the outcome of the United States Grand Prix having fallen short of 'the result he wants' in recent races.
Following a dismal start to the season, Stoner has inched his way back into contention with a trio of podiums in the last three races to push him ahead of Ducati team-mate Nicky Hayden for fourth in the standings heading to Laguna Seca.
A race he won in 2007, the Australian speculates that he is still lacking the 'extra tenth or two' he needs to be a race win contender this year, although he is satisfied the progress is coming.
“Laguna is a circuit I have always liked because it's tough but great fun and it follows the natural undulations and direction changes of the land. I also enjoy the raucous but respectful atmosphere that the American fans provide.
“Naturally I am looking for a good result but I don't want to make any predictions because recently we have been close to the front without managing to finish with the result we want.
“We're not far off - we just need a little more grip, stability under braking and handling, which would give us the extra tenth or two we're missing. It is not much but at the level we're at it will be noticeable. We'll see what happens but the objective is to improve on what we have done so far."
