Avatar Nutrition and exsessive weight loss

After having not lost any weight for 3.5 weeks, I've lost 10 pounds in the last 10 days. I use a diet app called Avatar Nutrition. It adjusts my calories/macros to make sure I loose a set number of pounds each week. I was afraid that since I lost significantly more weight than I should have that the program was going to increase my calories an excessive amount. It didn't. It only raised it 100 calories. There seems to be some kind of fail safe on the program that prevents to large of increases or decreases of calories each week. The longer I'm using Avatar Nutrition the more I'm liking it. I've lost 54 pounds since September 5th. Another 50 pounds to go to reach my goal of the 242lb powerlifting weight class.
