The "goal" lines are not even in the same area, the current line is much higher than the original one and as you said it is zoomed in. I don't know if this is meant to be intentionally misleading or if westonci if misleading himself.
If you zoom out, have the same lighting and taken not applying liquids (which make hair look darker than it actually is) then it's very likely that the gains are very very minimal, I mean a few vellus hairs minimal. It's been almost a year now, people should make their conclusions based on that.
