Mist: the poor man's Storm

Does Storm change precision by the same amount (6) or more? and are there any other differences?

For what I've seen, Mist does not reduce missile range, and yes this contradicts the manual.
Mist gives -6 (or is it -5) to all units, as a lump sum. Storm gives -50% precision, but does not affect the experience/air magic bonus.
So no difference between Storm and Mist for the classic, prec 10 or 11 archer.
Curiously, those spells are cumulative (I expected to see the fog removed by a good storm, but no).
FIY Darkness gives -75% prec.
