On the WTT at Catalunya, ghosts seem to be slower than the time they originally posted. I've raced my own ghost, beaten it but not been shown as any faster . I think it's a ghost issue, rather than timing.
Below are screenshots of an example. I selected 'Shamil F' as a ghost with a time of 30.657, yet when I end the race their time is 31.093.
Anyone else seen this? Is it a bad sign? (I haven't borrowed or cheated, but who knows.....)
