Just has a look at 5.2kW and it's at 79%  - mainly depends on your turns ratio, which likely effects efficiency at some power levels. BTW I had a chance to do Wiseguys efficiency test today @ 3.2kW and it was between 97% and 98%. I feel I should recheck the AC power Meter again at that power level just to be sure, when I get a chance.
