To Darren: Since worlds are only going to be happening once every 4 years, they will not go towards RPS. The Nats will count. While we keep the best 5 scores for the season towards the RPS, as part of those 5 scores, we allow up to two of your final scores to be from outside of the region. This accommodates folks that live on regional dividing lines where they can hit contests outside of their region more easily than some in their region.
On the sim, it isn't very realistic for IMAC especially however, if using real flight, make sure you are set on advanced and highly recommend that you add at least 15mph of wind in some direction or another...
