I can't believe SP gave you a range of 1200-1550, unless you maxed out on how fast you want to lose. I am 223 lbs, and the range they gave me is 2,470-2,820.
Have you entered you exercise calories burned per week? If not SP has you at burning 0 calories, which if you burn 100 a week, will increase your range. Another thing that might help is to set your goal for 52 lbs a year from today, which will up your range also. If it is 2 lbs a week, you have to eat 500 less, or burn 500 more than if it is 1 lb a week.
After that, stick to your range. Sometimes we plateau at a weight we stayed at for a while on the trip up the scale. I was stuck at 300, 260, and now 215 seems to be a barrier I am struggling with. Eventually you will break through, and drop weight quickly for a while. I think the body needs to adjust sometimes.
