6k season tickets is probably excessive but it would free up a few k of general admission by default.
But that means less additional general admission.
It's just basic maths.
Let's argue there are 15k GA tickets available.
If we add 4k more. That's 19k available. 2k further season ticket holders. Let's argue and say ALL of the. Are currently on 13+ and guaranteed so we have 2k fewer people going for 19k ticket. Keeping the maths simple if we have 150k now in GA they had a 10% chance of a ticket. The 148k now almost a 13% chance
If they made all the additional 6k STH we have 144k going for the same 15k GA seats. So the odds are only just better than 10%.
Anyone currently far enough back on the season ticket waiting list, it's better odds for more general admission tickets than reducing the waiting lists.
I know that's basic and discounts a lot of variables (not all those on the list are necessarily getting tickets.)
