Even though the deadline to enter the Finals is October 9, just like always you still have thru the last trial (Armadillo) to get your 5 qualifying runs. The Finals refund date of October 27 corresponds with the Armadillo entry date - so if you aren't able to enter Armadillo and you don't have 5 runs, you still have time to get your Finals entry fee refunded.
So go ahead and enter the Finals! Several nice Fall trials coming up!
