Ready-Go's are the same conditions (green speed, general wind strength etc) for everyone because they are tierless tournaments. Only tiered tournaments will have tier-specific conditions.
tiffer: Shoot an email off to members@worldgolftour.com and let them know the tournament #. They should be able to see what happened there.
*edit* There is kind of a "holdover" let's say when you look at one ready-go leaderboard and then immediately look at another one right away. It will display the first tournament's remaining time for just a second while Flash catches up, then it will change to that specific tournament's time. I'm willing to bet this is what happened to you.
