The biggest note here of confusion from the beta (see screenshot). The metric here is change in ROI. So, you'll see my ROI on month has gone up 51%, and the week has gone down 1.3%. If you hover you'll see the window of time it's comparing. Eventually, I'll rework this a bit and have it display the actual ROI % in addition to all this. Wasn't happy with any of the ways I implemented it in testing.
