The forum search can tell you if the grafana dashboard is showing the numbers including or excluding expansion factor. For example here: Publicly Exposed Network Data (official statistics from Storj DCS satellites) - #30 by Arkina
The rest is simple math. I have given you some numbers. You can try to make them match the grafana dashboard and you will quickly find out our internal dashboard has to show the same otherwise it would have to show a different scale.
