Got this in about 30mins. By far the easiest accelerator for me, which is strange because this used to be SGM and I assumed was the hardest of the Accelerators. Still 2 off on Neutron and Electron, and 6 off on Neutrino and all out of ideas on those.
(sometime in Dec. 2022) To Yokosoo:
I haven't beaten it, either (am 8 off). Since you were asking for hints, I hereby leave you an invitation to Discord (forum), where you can talk to players. I hope you will find this and join us there. :)
Apologies to David, I couldn't think of any other way, how to give this INFO to yokosoo.

EDIT, 13th Oct. 2023: I was 8 off, here, for a very loooong time. Was trying it, on and off, occassionally, but could never see better. Today was THE day. :D I finally saw what else I could try (which did not seem completely off, even before trying). And I came 2 off. It probably took me about 10 minutes more to find the last two steps.
GREAT Accelerator!
Am 2 off on that level and struggle to cut the last 2 steps. Will not give up, but I lack the time to spend much time on it.
*** somewhat later ***
The amount of 2 offs is crazy because there are 3 locations where minor variations lead to same amount of steps at their exits... It's hard to decide what one allows for cutting... LOL
*** Again later ***
Got it! Happy me! I was almost certain that one of the 3 locations should be the one, because it had so many different arrangements possible leading to 2 off... And yes, that was the one and I finally achieved to optimize it to cut the last 2 steps.
I so love such levels, would give it 6 starts if it would be possible. :D
I think I got pretty lucky here. Spent a couple tries feeling out the level, and then my first solid attempt at some shortcuts gave me a 255. Next try I found the remaining 2 and got the 253. From the sounds of it there are some other close paths so I'm happy I was able to avoid those.
Great level! I found a 2-off pretty early on that felt good and I was right, but I lacked the conviction to follow through...
Loved solving it!
[04/2023 edit] I updated this review so it's a lot less explicit in hinting :-).
(13-11-2022) 2 off currently.

(19-11-2022) I have been trying daily and found another good 2 off, but still can't see the correct cut. Really very difficult level!
Still not yet solved it, any hints for that? 🤔

(20-11-2022) Thank you alazeh and David for your replies and encouragement! At least it is good to know that this level is still possible to be completed, and I am not alone to be stuck on this difficult level :)
Maybe I take a rest from this level first and try to come back with a fresh mind later.

(21-11-2022) Thanks VisD for your comment! Yes, I had 2 quite different 2-offs. I retried those 2 again but to no avail. I believe my problem is still over the upper main part.

(9-12-2022) Have taken a rather long rest from this level, and after seeing the Discord discussion, I had some motivation to try this again. Indeed the 253 approach was something that I have tried before but I did poorly. 300+ tries from me so I guess I contributed much of the solving time for its Super Grandmaster difficulty. But it indeed well deserved its place - after completed this level, I have finally completed all PP1 levels available as of today.
Kinda annoyed at the 253 route. It was what I was doing originally before I had my route polished. Never came back to try it when I knew the rough path. Very solid level with a few close setup paths!
