  Richard and Peter,

      FYI -- this comes from Marv Gozum, MD, one of your DAN guys.

      Nice stuff.

     Expect his aggressive recreational data is of interest to DAN --  27 Vyper
  RGBM repet dives out to NDLs. Interesting comments too -- guess he is cool.
  Know that Suunto Vyper is compatible with your interface,  He's one of
  your DAN referral Docs, so maybe he's contacted you already.  Hope so.

     Here at LANL, his info will go into an "abbreviated" data base along
  with others, mostly tech, deco, mixed gas, because it's closer to our
  "envelope" of interest.  Will talk about this at the DSDMS Wkshp in
  Tampa -- just a bit.  Also NAUI Tec Ops has another for tech diver
  training off RGBM Tables.

     Best regards

 BW

>>Dear Dr. Wienke:
>>
>>Thank you for sending the updated pdf on the RGBM!
>>
>>I just pushed your recreational algorithm to its limits on dives using the
>>Suunto Vyper, which is reported quite conservative.  While I've 50 dives on
>>the Vyper, it was not possible to compare it effects until one did a
>>prolonged series of extreme NDL dives.
>>
>>I am impressed.  Details at a later time, but 4 daily Vyper dives for 27
>>total dives in the depths of Little Cayman, each 60-100 min long, did not
>>tire me as similar dives on a Genesis Resource computer totaling 300 dives
>>[ Powell-Spencer derived algorithm.]
>>
>>There are many subtleties to the execution of the algorithm that are not
>>reported in reviews, as no one has pushed the computer to its NDL
>>repeatedly over time and noted its response.
>>
>>Details later.

>>Sincerely yours,
