Wow, that took a while to validate! The winning entry is 13301142, owned by User 0117. Congratulations to Adam R, who is now a two-time winner!
Some users have a lot more computing power than others, and so are that much more likely to win the draws. Although this is to be expected, we are looking at how we can level the paying field a bit for the smaller users so that multiple winners become less likely.
Update to follow!
