Yes, I was wondering essentially the same point: the Blackfly has a sloped surface under the bumper (IIRC) and so it has a fair bit of air flowing under the car. Some of this air may be escaping out through the front wheel opening? If so, then the front skirts may be obstructing it and causing more drag than they save. Maybe with a full underpan and/or a front chin spoiler, the front wheel skirts could then lower drag?
