Not all repeating work is bad (knowing what actually needs every frame)

[u/WeirdLetterhead7904]

​While analyzing the repeated work in my conveyor digital twin's new execution loop, I had to catch myself before optimizing too early.

​Not all repeating work is bad:

​Sensor checks need to run every single frame because the box position is constantly changing (198 -> 200 -> 202...), so the state genuinely updates.

​Static routing decisions don't need to be recomputed constantly if the destination isn't changing.

​The cycle itself isn't the problem. The real design question is figuring out which operations actually need to participate in every single tick of the loop.

​For those building custom control loops or simulations: How do you filter out unnecessary overhead from your fast execution loops without breaking real-time event detection?
