I'm still completely confused; what is the time period (if any) you have to have bought RP in to qualify for this? Is it lifetime? This year? September-November 13? Becuase it sounds like you're still saying October 1 to November 13 which is what it was in the first place.
I bought 3500 RP using a 25 dollar prepaid card on october 5th. That qualifies me for tier 3 icons. However say I had bought it in september. I do not qualify for any icon unless I spend the RP during the period of october 1 to november 13. So I can spend 1000/3500 RP and qualify for tier 1 or spend 2000/3500 for tier 2 and on.
