There is a downside. Free accounts have some time restrictions, so between two consecutive processing sessions, the program waits about an hour. If you guess correctly the first time, you immediately get the result and can forget about the neural network. If not, you'll have to try again later. In my opinion, it's worth it, especially since the waiting doesn't force you to do anything else: switch tabs and forget about it for a while. Overall, the difficulty of the contest is roughly comparable to the difficulty of the dollmaker contests.
