Seems that either some have a different track or there is a bug that allows some to take the shorter track. I was wondering why I was 12 seconds off the pace.
I did a follow of the top time and was beating the Ghost and suddenly I was 35s back. I followed the Ghost the next time and off the track it went, right through the wall just before the hairpin mid track.
Is there a iPhone bug? I am on Android and could not follow.
