My el cheapo 12v switching supply is reading 184 watts at the wall while bertmod says 133watts.  If we ignore the BBB, I suspect bertmod does, the efficiency is 72.3%.  If I scale up for a Jupiter it's 736 watts at the wall.

I confirm BertMod ignores the BBB and also that the readings from the DC/DCs might be a few percent off (I'm not sure if the readings are temperature compensated, and the DC/DCs usually run quite hot, so there might be some error induced by that)

72% efficiency for a cheap power supply sounds totally possible.
I notice my temps are green, 37.5°C while others' are red.  My ambient is 66°F.  I built a wind tunnel and put cardboard inserts between the VRMs and the ASIC.  Don't know where on the module the temp sensor is.

Mixing imperial and metric measurements is confusing and just complicates things. 

Sez a metric user.  I have my Garmin GPS sports watch set for kilometers but record miles in my log.
