In this case, no reasonable grace period was allowed, as the vehicle was on site for less than 10 seconds, which is significantly less than the BPA's minimum grace period of 5 minutes.
I'd be mindful of this wording. I would suggest saying "the evidence provided only covers a period of 9 seconds, and does not demonstrate that the vehicle was there for longer than the minimum consideration period... etc. etc." or "the photos taken only cover a period of 9 seconds, and no evidence has been provided that the vehicle was there for longer than this" or similar.
