Yeah, I thought they'd do that.

That's why I put the exact amount in parenthesis (1.2 miles for every $1). Same thing with the DBS Altitude AMEX, it's roughly 83 cents/mile but in parenthesis the exact wording is used: 6 miles for every $5 spent. They also round down, so if you spend $9.99 it's the same as spending $5 in terms of mileage accrual.

Or maybe I should do it the other way around and write: 1.2 miles for every $1 spent, rounded down to nearest dollar (approx. 1 mile for every $0.83)
