Everyone here hates cardio. Me--I love cardio, but I hate the elliptical. Not hard enough. Couldn't get my heart rate to 75% max no matter what. (I mean, if you turn up the resistance a lot--i.e., to the point where you can hardly pedal, then it becomes resistance training, but if you set the resistance to a range where you can pedal, it's too easy.) I'm a runner, and since I'm currently training for a race, I'm definitely doing chronic cardio. Chronic cardio = weight loss for me though. I wouldn't obsess over whether something is chronic cardio. If you feel good doing it, then you're probably okay.
Edit: I will probably be stoned for this, but if the elliptical isn't helping you lose the 2 pounds, try running. You may not need to run 45 minutes 5 days a week either. Running is more intense so you don't have to do it as frequently. When I first started working out, I did the elliptical. (I was really unfit so the elliptical was all I could do.) Didn't lose any weight at all even though I was doing it 5-6 days a week. Once I started running a couple months later, the weight fell off. When I first started running, I would run 2x a week and do the elliptical 2x a week. That worked for me.
