The airdrop for the 31st has just been announced. It seems to be on the 31st, but actually, it is based on today's score, which means you can double dip today.
Three o'clock in the morning is too eerie. I remember there was a new launch in March or April that also happened at dawn, just to avoid the studios...
At night, it feels like the score will be very low, and there shouldn't be anyone competing with you.
