Your values are way high--according to the web site offered earlier (now at
home without the URL) the normal range for a human is as high as 600,000
ohms (dry) and as low as 500 ohms (wet).  Knowing that coming into contact
with 120 VAC is usually 'shocking' these higher values seem to be 'out of
the ordinary'.  At the 600,000 ohm value, you'd only draw about 0.2 mA which
is below the threshold of feeling.  At my figure of 100,000 you're at 1.2 mA
and certainly feel it.  Your figure of 200k wet would make you quite safe at
house voltages--but 500-1500 ohms gets you into the respiratory paralysis,
ventricular fibrillation regions.
