I was getting 1460w avg at the wall on NoDevFee firmware with manual chain settings ranging 625-675m(Did not have the Rocket version by Taserz on hand to try)

After 20 minutes the wattage settled at 1268w and has been averaging that for last 16 hours and counting.

I was hoping the Braiin OS would work on my S9 13.5T but I will have to wait for them to include it, hopefully soon.
