Wet Location Body Resistance

What body resistance is assumed in wet locations vs dry locations? I have a feeling Table 41.1 does not take wet locations into account.

    Any idea how this translates into a disconnection time? 


    As a first bash realise that the disconnections times quoted for  230V TN systems assume a touch voltage of 110-130V, and for TT systems a shock voltage equal to the full mains voltage is assumed. And if you then look at the figures for say 400V and higher then that is comparable to a system at half the voltage in a 'wet' condition.

    From what I'm seeing 100 volts is assumed  vs 115 or the max of 132 volts (110% of 240). Which just by itself is making me question what value to assumed for wet locations.
