I come in peace. Been reading this thread with interest and also wondered as to how they might be implemented.
This comes on the day that it appears the government website ran out of test kits apparently and with supply chains and actual contracts being what they are who knows what the availability of tests will actually be in the new year.
As regards capacity, it would be interesting to see how different grounds can/will interpret the rather odd rules. Will they simply go off total capacity, go off a general average of overall crowd, or is there scope to treat each stand as a separate entity?
Personally, logical fallacy or not, I'm not a fan of these types of measures in general, where they are heading or the division they are already clearly sewing and I too am waiting to buy my season ticket based on what will be invoked.
