On the start page you have a " Calories to burn section. figure out how many calories you burn weekly, and hit change goal. The last item on that page is a place to enter calories burned if you know what they are. type that in and hit save. This will set your ranges.
You have a range because no one hits 1700 daily. They have variations, and may be at 1600 one day, and 1800 another based on differences in the menu.
As long as you put in your goal, and how long you want to take to achieve it, then just follow the SP ranges. Yes, you will lose weight. Most people choose a lb a week, and so they have a 500 calorie deficit. So the top of the range is still 150 below the calories you would need to maintain, with probably a little extra room, since they don't expect you to eat 1560 every day.
I would think that they would split the difference, and 1735 would be 500 below your maintenance level. So 1910, would still be 325 below, and you would just lose a bit slower, more like 1 lb every 11 days, instead of 7 days. and 1560 would be 675 below, and you would lose a bit faster, but this might make you hungry, if you aim for the bottom end.
I would suggest you just aim for the middle of your ranges, and give it a few weeks. Then instead of wondering how it will effect you, you will have data to base these decisions on.
