He are a few suggestions to your questions| 1). --surfacing bubble volumes across all compartments we're used in risk function formulations, not separate compartments nor M-values; 2).-- NULL set means no,fits can be better, nothing more nothing less...

All, Don!t get out here much so just a few quick comments while I have time: 1) -- RGBM licenses are necessary legal comtracts to protect both parties and the integrity of the software whether we give It away or sell it; 2) -- would love to see and hear more about those...

Kevrumbo, Kern, Carlisle, and Jrock Thanks for the pointers and comments too. Gjaws COMEX tables were not originally deep stop (maybe changing somewhat), and don't recall that arterial model was/is used in their tables (maybe also changing). BW

hqfrogman, You are certainly welcome. Yes, if you read the paper, you'll note that we have 2879 actual (computer downloaded) profiles across mixed gas OC and RB systems. Our conclusions and risk analyses are based on that collection -- not a single air dive to 170/30 (NEDU) without...

Funky556, gkndivebum, lowviz, Randy43068, Saturation; Many thanks and you are welcome. gc; Sorry you didn't connect dots -- they are all out there in RGBM published papers and books. Maybe try asking specific questions? BTW, some 25-35 "folks" out there have successfully...

Thought many of you on SB would be interested in this recently published statistical validation paper for the LANL deep stop model (RGBM). We have been collecting data (ongoing effort) from our C&C dive operations for the past 5-8 yrs or so, and finally had some time to publish the data...

SB Folks, Expect many of you on Mike's Dr Deco Site interested, so am happy to post upcoming USN/UHMS/DAN/NAUI/PADI Wkshp on Lists. Here it is -- News Release and Schedule. News Release: Theoretical and practical solutions as to how to ascend or decompress after diving have been...

Steve, There's a book called High Altitude Diving that explains how to compute wait time for altitude excursions (FAD is a subcase to 9000 ft) using the repetitive group approach. We developed it here at Los Alamos National Laboratory, and it has also been sanctioned by/for...

Just FYI. Just back from a USN ONR/NAVSEA/BUMED Review/Wkshp in Baltimore. NEDU will begin man trials on deep stops, and this is monumental for the USN. Pairwise correlation of air dives to 170 ft for 25 - 35 minutes will commence in January, with one dive classical (Haldane-like) and...

FO, All of your questions are answered in DASL -- effects of dive depth, length of dive, wait interval before ascending, etc, etc. Plus the effects of repets. BW

FO, Every 1000 ft of elevation increases your actual dive depth by roughly 3.6 % as far as using sea level tables. This has been widely used, accepted, and tried at altitude for dissolved gas tables (USN, Buhlmann, etc), and holds with slight modification for bubble tables up...

All, There are a couple of addenda to the above and a few corrections need be made -- coming from both (my) USN/LANL diving experiences of the time and model diving correlations over many years and venues: 1) the oxygen window was not the criteria for staging in the...

Guys, Just one last item before I head out. And thanks for all the questions and comments across all threads and posts. The new Suunto RGBM Deep Stop computer is not on the market, yet. But will be. Estimate 4 months from my discussions with Suunto and Sten...

TT, The newer SUUNTO computers will have full RGBM deep stops. The older versions use RGBM bubble mechanics more sparingly -- mainly for reverse profiles, altitude, closely spaced repets, and high frequency multiday diving. MARES and DACOR (rec) computers have fuller versions of...

Right On, ICENI. Columbus sailed the wrong way too.

TT, Suspect you were in a light deco situation controlled by fast tissues linked to small bubbles on VYPER. Both fast tissues and small bubbles "washed out" on way up. This happens often in shallower, light deco situations. Bruce Wienke Program Manager Computational Physics C & C...

Listees, Have been asked to pass this onto SB -- great historical perspectives from the Father Of Modern Decompression Theory. Is part of article from SOURCES. BW Some Early Evidence for Models Dual-Phase By Brian A. Hills Editor’s note: Brian Hills was one of...

List, Just FYI and some are already familiar. Mark Ellyat (UK) continues in his quest for world record OC dives on trimix using modern deco strategies. These stratgeies include eliminating nitrox switches (keeping N2 levels low while minimizing isobaric N2...

Yo, Got an email for some clarification on questions on this thread. This info has been posted in a bunch of places before, but hope this helps here. :) Recreational RGBM is a subset of full RGBM for no-deco to light deco diving. Full RGBM is used to correct for short SIs...
