Why does this site show ranges for some tower facts?

Official sites, engineering bodies and news reports sometimes give different numbers for the same thing. We do not pick one quietly. When sources disagree we show the range and name each source.

Where they conflict we trust sources in this order: Emaar and the official tower site, then the Dubai Land Department, then the Council on Tall Buildings and Urban Habitat, then Wikipedia.
