It's not difficult at all to pro-rata last season. For those saying it is...
Full season... 19 games with 13 games the magic number.
Which translates to , if you attend 68.4211% of games in a 'normal season' then you're guaranteed a ticket.
So let's use that same formula for last season.
Last season... 15 games played, what's 68.4211% of that? 10.26317, call it 11 games if you want.
Again. Not. That. Difficult.
The problem is the time people invested last year in getting tickets has been completely discounted. Ignored totally.
I do get that you can't just assume people would have got tickets for any remaining games, totally. Which is why pro-rata makes sense. This takes into account the actual physical time spent by people in getting tickets.
