I must have misunderstood the AA system to reach ExP. I thought with Plat challenge you could achieve Plat Stat after a long DONE based on starting SYDJFK D/Class (Plat status reached) then six USA sectors in A/class at miles + 50% +100% then the remaining sectors to total 20 at milesage + 25% D/Class+ 100%. If this is the right calculation then it shoud not be that difficult to achive 100,000 miles in one RTW.
