There's this thing called sandbagging in motorcycle racing. You've probably heard about it. It's where a rider doesn't show his hand completely ahead of the season, doesn't smile in public, hangs a tale of woe on the media, about how he is struggling with the bike, and how much work they have to do. Then, when the flag drops and the racing starts for real, the rider goes out and completely destroys the opposition.
The key to sandbagging is not to give too much away on the timesheets. Riders find all sorts of smart ways of doing this. Working on one sector at a time, perhaps. Pushing for the first half of the lap, then backing off for the second half. On the next run, they back off in the first half of the lap, and push for the second half. The bare lap time shows up as unimpressive, but put the two halves together and you have something very impressive indeed.
Marc Márquez appears to be trying to sandbag at Phillip Island, but he is not doing a very good job of it. He has the act down just fine: lots of criticism of the bike, a lot of concerns about which areas still need work, pointing out that Phillip Island tends to hide the weak point of the Honda RC213V. The point where he is falling down on is hiding it out on track.
