Certainly interesting data, although Im not sure it necessarily implies that there is an 8.3% chance of it being today, just that historically speaking past releases had an 8.3% rate of appearance on a Friday. That in itself doesn't necessarily have as much impact on a future release as they are independent events essentially. But, yes, in the overall "feeling" type of sense, it makes it appear that Friday is somewhat less popular or perhaps even likely than some other weekdays.
You're right, I may not have phrased it accurately, but that's what I was getting at. Still hoping to see it today, though
