Notes:
1. the FFC Nurburgring, which takes c15 mins, is the second fastest repeatable XP/hr earner before level 40 (after the 24Hr Le Mans).... thanks to SmokingCones who also worked this out.
2. if you complete the SE7 events and then win 13 x FFC Nurburgring (ie one per day while SE 7 are up) you will get 600,000 XP.
