OK, this one is REALLY only of interest to scripters, but the way the fWait setting gets used to determine script likelihood is as follows

there is a 1/fWait chance the script will be considered for inclusion in the current mission list,

i.e. an (fWait-1)/fWait chance it will be discarded out of hand

So scripts with fWait of 1 are always examined,

fWait 2 gives a 50% chance of being considered

fWait3 gives a 33% chance of being considered,

etc (no apparent upper bound)
