VIC Infringement notice missing checked box. Technicality?

Hello,

I was booked at 34km/h over the speed limit on my motorcycle, and the officer did not check the box that says:

"(if box is checked) This notice relates to an excessive speed infringement and it will take effect 28 days after the date of this notice as a conviction and -"

She did check the later boxes for 1 month suspension.

I am wondering if this omission may allow me to avoid certain parts of the infringement; for example:

1) Conviction
2) 28 day delay

On point (2), perhaps it could be argued that without the clause being included, notice reads like there is no 28 day delay, and so my term is already almost completed.

Is this defensible, or should I just cop the penalty?

What I meant to ask is: that checkbox is there to record penalty and process. It is unchecked. Does it mean nothing in my situation? If not, how does that alter the infringement terms?
