Yeeeeey, I finally found it. :))
Before that I had a two off, wondering if it was to be optimized. IMO, in a level like this, optimizing means something different, not just moving one block for one step, later, for example. I think it's about setting a position, that will ''save the loops'', somehow (''make them shorter'', HAHAHAH, however unintelligent this might sound :)) ).
Levels like this are very hard for me, but also very interesting. While searching for 233 here, I had even one variation where I didn't spend all the blocks. But did not explore it further ... So it might also be something there. Just not sure. Might come back, some day. But for today I have maintained conveyer enough, I guess. ;)
these sectioned/block timing levels are tough. I don't feel very strong on them. Too many things feel good enough to be optimal and then are just... shorter routes. Hope this 233 is optimal because IDK. feels tight enough to be good though.
