2. Chris at Abyss seemed to have tried his best when RGBM was coming out. He produced a simulator, did lots of comparisons, got feedback from a wide base and seemed to be working closely with Bruce Wienke. Now problems arise on dives to depths where none of these algorithms have been verified, and people seem to be sueing each other, sadly, Bruce seems to be walking away from Chris.

Ellyat deserves what he got, and so does Chris for helping Ellyat.. The RGBM model as supplied by B.W. is specifically limited to 180m.. This is documented. The abyss implementation was a work in progress, and it only worked with trimix, it wasn't valid for other gases..

If ellyat wanted to do this deep stuff using abyss he should have stayed with the dissolved gas model within abyss.

Throught RGBM Bruce uses approximations for the various differential equations so his limits must be observed. This depth was chosen as the limit used in the approximations because around this point fluid shifts have to be accounted for and there is no real data on that..
