For the sake of disclosure, I am a bit under the influence right now, but what the hell...
I see one issue with your train of thought. If you read Rule 4.210(b)(5) carefully, the officer only gets the notice to submit his side of the story once the defendant submits TR-205 (the two-page form where you write your current mailing address and 'I am not guilty ^_^'), not the just the initial written notice requesting the TBD. The officer's deadline is NOT the same as defendant's. A couple of clerks from different courts also gave me similar info about TBD procedures, as well. IMO, arguing that the entry in the docket minutes trumps the deadline prescribed by Rules of Court is going to be tough, to say the least...
Besides that, there's also Rule 4.210(c), which gives the court a lot of discretion in extending the due dates for TBDs.
That being said, in my opinion, your best bet is to keep quiet and hope is that the Ofc. doesn't submit a reply by the 15th. Unfortunately, the law and the Rules of Court are not fully on your side on this one. If he submits a reply and you lose the TBD, time to prepare for TDN and figuring out how to set up as many grounds for appeal as possible.
