It's not your fault.
We've played the "Percantage" game before during Diagon softs and it didn't go over well. The answer is always going to be 0 or 50/50; nothing more than that. As we saw last week, they had a date in mind and something prevented them from doing Softs.
It's silly to give a percentage because there are people who will take it as a sign and plan accordingly. Giving a number a week out is pretty much BS because the smallest hiccup can happen and bring it down to 0%. In all reality, we will have a better idea when they're getting ready for Softs within 24-48 hours of the planned opening timeframe; and even then it's not a lock.
