Yes, a few years back they changed the points ratio on that end. It used to take about 500 points to get a $5 gift card and now it is 5250 points.
But they also fiddled with things on the other end.
At least for me. Maybe Bill Gates likes me or something and told his people "Make sure that pathetic homeless woman can earn $10 per month as my generous gift to her."
I earn a $5 gift card about once every two weeks-ish. I'm poor enough that matters to me, so it is something I am very aware of. That $5 gift card is sometimes still all the money I have for the day, though I'm less desperately poor than when I was homeless.
I don't know what else to tell you. Your info sounds out of date to me, but ¯\_(ツ)_/¯.
I was just doing it passively on one computer without extensions.
