lol you have spectular stats. dont worry. you're not really that late at all. you might be lumped in with the majority of applicants (most of which dont use SDN or at least people who dont pay attention to the craze of the early submission
) if you send in your secondaries now, you really wont be late at all, and all that will be left will be a simple rec that they can add to your file in september to be finished and ready for review. Sending later will just take longer to process since they have to wait til the check clears, then process, notify, put into the system, file away, etc, etc etc..
