keeps generating duplicate code as if it doesn't see lines off screen

when making minor edits, it sometimes just duplicates code

this instruction:
Update method2_5() so that for each delay step, it cycles emitters ON, samples and updates min/max, prints, then cycles emitters OFF, samples and updates min/max, prints, then ramps the delay. This alternates ON/OFF for each time duration.
