1.  I would trust the more conservative.
2.  Where is the trip report ?  :-)

#1 explained: The new generation of computers (Suunto's which I know you
now use) were modified according to some doppler studies of microbubbles.
I think that the difference between your computers is mainly due to this fact.

In my regular diving group, we have two computers with the modfied
algorythm and an older one with the former algorythm.  There is always a
difference in bottom times (the old one gives more bottom time).  We always
dive according to the new ones.  BTW, the diver with the old computer
claims that his computer is better because it gives more diving time :-)
