As with all formulas it's a starting point. I found an online calculator using that formula, plugged in my current weight (~250) and the number seem valid. However, I plug in the weight I was a while ago and they seem a little higher than I was easing (and losing well). If you're sure that your calorie counts are accurate (weighing a good percentage of what you eat), then drop your calories slightly.
The one thing to point out is that watch you aren't putting so much into your workouts that you aren't moving around as much the rest of the day. FWIW I'm also doing NROL Break-in at the moment with the intervals afterwards. However, I also add in some walking 5 days a weeks (well, with a smidge of jobbing, but that's because I'm a bit of a masochist!)
Oh, and when did you start NROL? (ie. give it some time as weight loss isn't always linear) I'm a daily weigher and will definitely put on at least a pound (sometimes 2) after a lifting day. So if you're only weighing once a week, just do it two days after you lift.
