I'd say wait. Pulling another SW just to see account changes is not worth it IMHO. sign up for a reg credit watch product, free trial for that. Maybe EQ advanatage. I'd use your SW pull for preparing to apply for credit rather than to see improvement.
If you fix the report and go through the motions, the score will come along. My focus has always been fixing the credit report and not the score. Save your pull for something good IMO.
Starting Score: 501
