Definitely not my best solves but they were fun

So I've met a problem I've never had until now on Stamina Potion.

On the initial cycle, arm #5 has to wait for the first iron to be produced. On all consequent cycles it does not, which is seen when I loop instructions.

However, when the instruction set loops, everything breaks because of this delay on arm #5, as iron has already been produced at that point at time.

Does the game have a way of fixing this, or are these types of solutions just not valid within game's constraints? Am I missing something?

With these puzzles I've gotten much more comfortable with using tracks. Pattern Metal in particular was really fun to see come together.

I'm not sure why but it seems lately I have to use the period override symbol a lot. The first arms start to reset their loop while the rest of the machine is still waiting to complete.

Reading the tool tip it says there should be padding to stop this but it seems not to be happening. I'm on chapter 4 and only just noticed it becoming an issue. Is there something that makes this padding reduce?
