I don't get it. The survey invitations say things like "earn 90 miles" or "earn 150 miles" and I do not put enough effort into this to actually keep track of how many miles I am supposed to receiving, but I have taken a handful of surveys for them and other than the introductory offer, I have received 2 miles for one, 3 miles for one, another 2 miles, etc. Is this the experience others are having - that the invitation says they will receive many more miles than they are actually receiving? Like I said, I am not specifically tracking each one, but I have definitely never seen a survey that says, "earn 2 miles."
