As I’ve gained more experience with the Resistance Zero system, I’ve found that it works a bit better if the scan is done from the beginning to the end, and the dotted tasks are then actioned from the end to the beginning.
I’m also personally finding that it works best if the scan is done quickly without any lengthy attempts to decide whether a task is at zero resistance. So I say “No Resistance” at the start of the scan, but don’t repeat it again during the same scan.
