Everyone responds to things differently, so you really just need to know your body and how your body responds to different caloric levels and carb loads. You should be tracking everything if you aren't already and make small adjustments over time to see what works best for you. Only you know what carbohydrate level will produce the best results without adding fat. Carb sensitivity varies so much from person to person, that there is no cookie cutter answer. I know people that get fat on less than 200g per day, and people that are running 400+ while prepping for a contest. Your training and cardio change things as well, as it impacts how much carbs and glycogen you need for energy versus how much you will store as fat.
