hit your cardio as hard as you can before breakfast, and again in the evening. 9-7% shouldn't be that big a deal.
The problem with doing your only cardio before breakfast if you want to eat a tonne of carbs during the day, is at that point your body isn't relying on carbs for fuel, just fat stores (in theory). This is fine if you're eating a typical carb reduced diet for cutting up, but if you eat alot of carbs, then its not really optimal. So, try to do some cardio again in the evening when you're carb loaded, and that should help directly burn some of the carbs you ingested during the day before you go to bed, and it gets turned to fat.
Once you hit your 7% though, stop the evening cardio for sure, no need to risk burning up muscle with too much cardio once you hit your goal!
