There is no 95th, just sum of all usage, from what I gather we have two options Total Power - put billing option on Total power and just tally up the already calculate kW the PDU will deliver. Phaes Current Mesuring - more in-depth, can monitor separate phase if they are being used for diffeent services/customers. This requirers a small calculation to build the graph (Voltage*Current=Watt), basically multiplying Phase measurement with the Voltage measurement). I would prefer Phase Current Measuring both because it gives more control what you are measuring and because Im not sure all PDU will deliver a total power calculation https://cdn.discordapp.com/attachments/327529583601647617/1513534132813168650/image.png?ex=6a281401&is=6a26c281&hm=aa158b55f5433bf20d54f040b269cd0d928c0e7bc331342c8cd139b38938d33f&
