Question is .. why are you worried about "good' ratio.
75k EQP / 50k EQM would get you nothing more than PLT. 150k EQP / 100k EQM would still get you EXP. Your example of 95k EQP / 105k EQP will still get you EXP.
If you make a tier on points or segments or miles .. you make the tier. Most times I make it on all three!
AA has no 'above tier' program except Concierge Key .. and none of us know what the "good' ratio it requires is!
