If it's any consolation for young you, this is a really hard problem, even with electrodes implanted in the brain. There's an amazing podcast by lex with the team from NeuralLink, and they go into depth on how even with good neuron signals, there's still a lot of work on the software side to "moving a cursor". The first recipient of their implant still has to do a 10-30min calibration run every morning to be able to move a cursor reliably on the screen. So all in all, don't beat yourself up, it's a really hard problem even with good data.
