Did you get that from the FAA Chief Counsel, or an attorney with an aviation practice, or is that just your own guess? Personally, I don't think the FAA Chief Counsel would agree with your legal logic, since the attendance did result from the ticket -- without the ticket, and the points it accrued, you would never have taken the class (ask an attorney about the "but for" test). Absent a Chief Counsel agreement with your logic, omit that attendance at your own serious legal risk.
That said, I discussed the original issue today with a Virginia-licensed attorney familiar with this problem. He said that the reckless charge is automatic for any speeding offense more than 15 over the limit, and the only way to beat the reckless charge is to hire an attorney hooked into the local judiciary where the case is being tried. Other than that, you will eat that reckless charge.
