If I'm reading the numbers in the article correctly there are two issues at play. The first is that in normal ISO values the camera over-reports the ISO. So to get comparable exposure to other cameras +0.72EV is needed. The second is that ISO3200 and ISO6400 don't seem to be actual sensor ISO values (at least on the XT1). They seem to be ISO1600 underexposed by 0,66EV and 1,66EV respectively (or maybe only 6400 is 3200 underexposed by 1 stop). Apparently there's even a raw tag that specifies the needed compensation. Don't know if we're already applying it automatically. Fuji does like being weird...
