My initial rough analysis years back lead me to conclude that the returns just wasn't worth spending on cards which gave Miles as rewards. It's quite hard to quantify Miles, cos... well, that's the point, they don't want it to be easily quantifiable... so consumers won't know how much they are spending vs how much the Miles are worth.
