Yeah, the BMR calculator is supposed to calculate your basal (resting) metabolic rate. The link I provided has both BMR and maintenance calculators. The statement about calculations being for sedentary individuals is likely meant for the maintenance calculators. Those calculators are really, really far off. That's why I base it off of the BMR calculator, since, although they aren't exact, they give a much better ball park range.
BMR is essentially the number of calories your body needs to survive if you laid in bed all day without moving, eating, thinking too much, etc. It is the minimum anybody should eat to maintain their metabolism and still lose weight. I'd say try to make absolutely sure you're eating more than 1700 calories. When I cut, I weighed less than you and took in 2200 calories per day. IMO, I'd say eat 2000-2200.
If you stop cutting, you're likely going to need more than 2500 calories, especially with those activity levels. I typically do 2-4h of intense cardio per week, but when I do it, my caloric need is over 3000. Essentially, if you're not cutting, make sure to just eat when you're hungry. Unless you have poor hunger signaling, that should be enough to tell you how many calories you need.
I mean, I imagine the only thing limiting you would be recovery (through sleep, diet, hydration, low stress levels, etc). Remember to work into an increased level of activity so you don't injure yourself. Then all your hard work, cutting, lifting, and running would be all for naught.
