Repeater wasn’t necessary, it costs too much memory and is not very efficient when it comes to interval, try replacing repeaters with trigger loops, set trigger trigger on [channel 1] and trigger on [channel 1] when triggered, set the interval/delay to [1.0 second], it costs way less memory and can be more useful when associated with block code.
I won’t say anything on the guide structure and quality for obvious reasons, just do better.
