I’m trying to work out whether the difference is we’re just seeing different amounts of distortion or whether we’re processing it differently. It’s hard to tell just eyeballing your distorted Input_3 input_4 in post 2, to my 60Hz 20A distortion plot which you can see in this post.
Could you attach the raw sample pairs for both the Input_3 and Input_4 plots of your post 2 above please? That will give me a distorted one and a not distorted one as a reference. I should then be able to compare your CT distortion levels with mine.
