Impossibility of Neuralink Compression Challenge

Apparently, someone solved it and achieved an 1187:1 compression ratio. These are the results: All recordings were successfully compressed. Original size (bytes): 146,800,526 Compressed size (bytes): 123,624 Compression ratio: 1187.47

The eval.sh script was downloaded, and the files were decode and encode without loss, as verified using the "diff" function.

What do you think? Is this true?
