I feel like there is a window with this, a verdict too soon would be more likely to be NG because it's easier to go through each one and say "nah, no evidence" quickly than it is to look at each one and say "Yep i'm sure here". But after a certain amount of time, which I have arbitrarily set at 6 days deliberating based on Allitt and Shipman and that it took Matt Goss 5 days to summarise, it would be looking at likely not being unanimous.
I feel like tomorrow/Monday would be in that sweet spot of a proper deliberation with a unanimous verdict. Middle of next week is when i'll start worrying!
