This has become a slightly jumbled and confusing post.
I would suggest that if you have run off in excess of 90% then you may safely assume that your still is refluxing, and doing it well.

Yes, it can also do this at lower abv's, I am trying to point you in the direction that most here go.
Refluxing is basically just sending lower abv spirit back down the column.
Most here would be happy keeping +90%.
I am, most of the time.
Mash admits to being out of his depth, and not all reflux stills rely on puddles, but he made a valiant effort.
