When you've run a time trial you get told which group you are in (A,B etc), your global position and your position in the group. We know the groups are 1%, 5%, 10% etc and from that you can work out how many people have raced in total (global position - local position) / (percentage for group) gives the number of players in the time trail. Shame FM doesn't give leaderboards for all events.
