I think that the entire discussion of how to add carbs in 5 grams increments until you figure out your critical level for losing is misleading. Most of our bodies don't seem to work like that. I can lose one week on the same level of carbs that causes me to stall another week. Partly this is because calories do count, partly this is because of fluctuations in other areas of my life (hormones, stress, sleep, exercise, etc.) and partly this is just because our bodies are not machines and don't always react the exact same way to the exact same things.
