Okes, they have to tick boxes. They have hoops to jump through in order to get the thumbs up to put on the event. These are to appease the government, not some scientific power that requires accuracy.
If you want to do the fun ride, jump through the hoops. If not, don't do the fun ride.
I'm sure the organisers also think some of what they have to do is dumb, unimportant and inaccurate, but, government.
So picking apart the bones of how this is going to run and complaining about everything is not going to change that the government laid out guidelines which we all have to follow.
We know the tests aren't accurate, they know the tests aren't accurate, but they have to be seen to be doing something other than ignoring it.
