Hi Rodney,

You wrote;
BTW, one highly respected doctor stated that the probability of a convulsion
for divers at 9mtrs on 02 was 1 in 12000. Durations/prior exposures were not
mentioned.

Wan't he referring to the Edmonds Table for IWR using O2?  This assumes
at least some prior exposure, and I think (off the top of my head) is
an exposure of up to 90 minutes at 9 metres.  (I could be wrong on this
one too) followed by a very slow ascent (12minutes/metre?).
