Marty - for Brits and Americans the timings mirror Clueless and mean that it’s all wrapped up within a few hours (generally) and not having accolades dragging on till the day clueless arrives again - so the competition stays brisk IMHO - as it was to begin with when I set it up.
For Antipodeans the timings work as contestants but not as setters - so they can reset closing hours to suit them.
