Well I have been looking over the list of Mario Kart unlockables and noticed a few items which catch my eye are unlockable through beating certain staff ghost data in time trials. I beat the 1st lot of staff data on the very 1st cup with little difficulty but now find my self really stuck on Yoshi Falls. No matter which Kart or Bike I choose, whether I follow the ghosts route or not I come no where near their time. It seems that the staff Data has somehow become super charged!!! I would consider myself an above average Mario Karter and come 1st - 3rd position in most of my online matches but these time trials are giving me hell - anyone have any tips? Another quick thing, I notice to unlock certain things a number of "Expert Staff Ghosts" need to be obtained - any clue on what indication you get to say the Ghost Data you race against is 'expert level'? The only information I see is the name of the staff member. As I mentioned above I have beat the staff data on the very first cup but the only Ghost data which is listed is my own records and the Staff ghost data I just beat..
