Hmm, so I'm looking at builtin-stat.c::print_interval() and since it gets the perf_evsel counters and you can deduce the counter name from it, you probably could match the rapl counters and do the Watts conversion above as a special case.
I dunno, it is much better than having some naked numbers for which people have to go stare at the sources + CPU vendor docs as to what they actually mean.
Thanks.
