My two biggest wishes for the Gigafinal are to have one in Scotland and for it to be in term time. However seeing the map of Megafinal locations, I see your point. It also raises some questions.
Do you have a similar map of all the schools and clubs running the first round?
If there was a Scottish Gigafinal, would it encourage more Scottish schools to enter/more regional Megafinals?
Has any analysis been done of the proportion of qualifiers that enter the Gigafinal vs the distance to the Gigafinal?
In the absence of a Scottish Gigafinal, how about a Newcastle one in June and therefore in the Scottish term time? It doesn’t really help the folk further north but it can be done from Edinburgh in a day, at least on a Saturday. The first train is unfortunately too late on a Sunday. As it’s on the East Coast mainline and A1 it would possibly appeal to East Yorkshire and Lincolnshire qualifiers too.
