I'm a relatively new miner here, and it took a long time before I figured out that red line has nothing to do with your ramp - It's just the average of the graph.

Look at your hash inside the red band, that is pretty much your % ramped (how far you have your full hash rate through the red band moving right/left, not the red line moving up/down)

I still have concerns (bad luck crossing difficulty changes and whatnot), but am keeping all of my relevant hardware pointed here and hoping to add more.  For now, I mine on.
