Wow what a path. I fiddled around with the idea a lot espeically in neutron but it just never worked for me. I'm not sure what I did differently this time but whatever it was it got me the steps this time. I'm amazed you can get such a different level from an exact copy with just 1 block changed. Amazing level.
I found for me what makes this level so hard is the "decoy" 2 off path is so good and filled with little tricks to make it shorter that make you think it's the correct path just slightly un-optimized, while the "janky" path that I was 4 off on that I assumed was the real decoy turned out to be the correct path. Hope this helps with neutrino, the last accelerator I am stuck on.
