IMO in a domestic situation it might make sense for Ze to be a declared value ie higher then actual or measured. And for all other test requirements figures should be to one decimal point. IE the test result requirements should be sensible not to exceed figures, which I don't think they are at the moment.

I did hear that the IEC wanted national standards makers to consider using a 0.67 fiddle factor for tables such as 41.2/3/4 in BS 7671. This would be instead of the 0.8 temperature adjuster.

I believe the view was that this higher factor better represented the uncertainties in EFLP testing generally.
