(Sorry I didn't respond to this sooner, I just got the full thread sent 
to me today)

You are absolutely right.  I was completely wrong in saying that nobody 
has been bent on MiG Plan.  We cannot have it both ways.  It was (until 
recently it appears) true but irrelevent that nobody had gotten bent on 
tables generated by MiG Plan.

That profile was not intended to be a sample of a dive that is safe or 
unsafe.  That post was in response to somebody who asked a general 
question about deep diving, I recall, and I was just relating they way I 
personally choose to dive.
