v1.9 wrong error pp and question to tissue/inert gas display

[Alex]

hi,

i thing i have found a tiny bug in the v1.9.
settings:
setpoint 1.6 on 6m (100% O2); BH CCR with GF

On the last stop at 6m and fewer the pp display 1.52 (that's right on 800m height above sea level!).
but the display is permanently switching from "1.52" to ">2.55" and back.

A other "problem": displaying of the tissue

The dive was with 9/56 trimix 10 minutes on 80m. The display show me the tissue 1 is the critical one (i think that's possible) and the critical gas is N2 and i think, that is wrong! the HE is more faster like N2 and in the time to ascent to the first stop the HE must be the critical gas, is it right ore i'm worng?

thank's for the answer and sorry for my english

the N2 is very nice/good!!!

Hi,

In the Bühlmann model, there is no such think as a >. Indeed, to compute the criticallity of the N2/He mix, the limits of N2 and He are averaged according to the gas ratio, and that uniq limit per tissue is used to test against ambient pressure.

Thanks for reporting, this has just been fixed for the next release.
