I felt stupid by how I understood the redeeming points. Though you loosed over all points but apparently you don't. So I've been spending it each change I get which gag ended up letting me redeem 3 times within a month. :D
I have no idea if I can get 7k within a week, never checked to see.
I waited quite some time so I can't say just by looking at the redeemed points...
so, I've started becoming really active by end of July, so that has been pretty much exactly 8 months for now. I have 24794XP right now, that makes about 101,6XP per day on average, so that's a bit more than 2 months to get a gift card (you're an editor and posted many mytakes, that gives tons of XP).
I had 2-3 months where I did more like 150+ XP per day but I'm not as active anymore since 2016, so it dropped quite a bit
wow... Well since I have no life at the moment it take me about 7 days tops if I gag 24/7 non-stop. But if school in the way which is 8 week course I usually can't! Because school first! So it take me 2 month or 1 month or like 3 months.
