It's worth noting that the thread says "up to 10%," not "10%" as the title suggests. So it's reasonable to believe the rate is as low as 5% based on the only real figure given (25000 / 470000)

I think our education system should include a unit on "marketing bullshit" sometime early in elementary school. Maybe as part of math class, after they learn inequalities. "Ok kids, remind me, what does 'up to' mean?" "less than or equal to!"
