It’s hard to tell when the loop restarts. Its one continuous line so guessing where it begins again is difficult. I recommend a visual change to make it easy to tell when your cross zero. Telepathic instruments orchid does a good job of this by putting a small space between the end and beginning. They also do these for each quadrent of the loop.
An option for a count-in to start the loop would be great.
Thanks!
