Gary, you finished 20th which is not a point scoring position - points are awarded to the top 18. However, as Luton had so many in the points, their last two didn"t get allocated points, and those points were awarded to 19th and 20th.
So, you scored 3 points for the team (nice one!), but didn"t actually finish in a points scoring place. I"ll adjust the sheet to show these 3 points and upload again after the next round.
