I don't understand why you want to down-rate people who are using more capable or more efficient hardware... is it necessary to demand they get paid based on how much heat they produce rather than how much scientific 'value'?

Wanted to comment on this too. As I understand the proposal, the network-averaged energy ratio FLOP/Joule for each (CPUs, FP32, FP64) is used only as a means to define the conversion from FLOP --> GRC within each class. The reason for defining the conversion factor this way is to allocate rewards more equitably between CPUs and GPUs. It remains true that FLOP is proportional to GRC rewarded within each of the three classes.
