Does the machine give you a count? I usually workout at home, but once a week during my daughters' gymnastics classes I have access to the fitness equipment that gym has, so I use their elliptical while my girls are there, and bonus, it over looks part of the gym, so I usually get to see them for at least part of their classes. Anyway, I use resitance and incline on that machine, and it gives me a calorie count higher than SP's. I typically average the two numbers and call it ok, since the machine doesn't have my height/weight/gender, but it does know my intensity/workout level and SP knows my height/weight/gender, but doesn't know my intensity, so I figure the average is probably a good guesstimate. If you don't have that info from the machine, and you are using it on the lowest setting, I think I'd just go with SP's number. You could also try to calculator over at caloriersperhour.com and see what you get there.
I am 5'4".
