I did in fact use custom tables when I did the dives (see my post from about
three weeks ago, "Gas & Air dives done").  I don't think the fact that they
weren't designed/tested for this use is an issue - they weren't designed to
be used as depth gauges & bottom timers on trimix dives, but work fine for
this.   The real issue is that they don't account for the fact that existing
He bubbles from the previous dive may make the Haldanean model too
inaccurate. Then again, I don't believe that custom table programs take this
into account either, except insofar as they may use different J factors than
the dive computer does.
