Congrats to David Felsager 👑 on winning controls challenge v2!
While the cash prize has been claimed, the #1 spot is still up for grabs. Scores <100 will continue to be added to the leaderboard.

Worked on this for a few days, haven't found anything better than what I tried in the first hour (delta encoding + huffman) with 3.41x compression ratio
Which is kinda sad since a generic block sorting compressor like github.com/IlyaGrebnov/bsc-m… can achieve 3.43x
200x lossless is definitely impossible since the last bit of the ADC is mostly noise due to hardware limitations if the original neuralink paper holds true
7uV resolution, 5.9 uV noise

Congrats to @Quantizr and @omarrayyann for winning our controls challenge!
Jimmy's PID solution got a score of 34.2, and Omar used RL to get a score of 42.1 to win the most interesting award.
We'll make some improvements and do another round!
