And another Noob-Question:
I'm always quite unsure about the Medal times to set: What happens if i re-upload a track? Will the old one be replaced? Or are there then two instances of my track?
I mean, if i see that there are too much Gold or Platinum medals I'm watching the replays of those, and if i see there is too much of an Error margin i would like to fix the times and replace the Track that is already in TrackCentral.
