Can't remember if I saw it here or at motomatters but somebody mentioned the differences between Stacey and Jorge's approach to FP. George runs endless race simulations (and hours / kilometers) on his bikes while Stoner did a few laps, made changes, did a few more, repeat. In total, most likely putting far fewer hours on his engines.
Perhaps Jorge needs to consider that, though I doubt he could. It's too much a part of his routine. Kinda like asking Rossi not to grab his ass as he leaves the pits.
