I was initially proposing a method that would use the regular OC depth dependent interpolation method with one modification: only the samples that represent an increase in depth to be considered, i.e., when ascending or maintaining depth, we would consider diluent consumption as zero. This method creates the problem of separating what actually is a depth increase and what is simply noise in depth reporting. Two methods where suggested to solve this issue: * a threshold (3 feet? something changeable by the user on preferences?) that would define the minimum depth change that we would actually consider a depth increase * a 1 minute time average depth (suggested by Dirk). I like Dirk`s idea but I believe any one of them would work. Regarding the graph you posted Willem, I believe that during ascends and fixed depths periods, the diluent graph should be a perfect horizontal line (no consumption as I mentioned above).
