At the sort of angles of bank normally used for climbing in thermals, the
difference in sink rate compared to straight flight is only a fraction of a
knot. The difference would hardly be noticable on a netto vario.

I wonder if netto variometers exist that indicate correctly during
turning?


In theory you could approximate the drag polar with induced and parasitic
drag. I am wondering if devices exist that do that and compensate for the
higher g factor during circling.
