Hi,
a while ago I was asked to add the average depth profile to divePAL becuase "some tech diving organizations use average depth for planning purposes"
So, we did it.
And now that we have average depth in divePAL, I wanted to see for myself if - and why - it makes sense to plan a dive using the average depth instead of the actual profile.
So I did an experiment: first I did a plan for a deep multilevel dive, then I obtained the average depth and use it to plan an almost square profile using that average depth.
And the results are quite interesting: for both dives the bottom time is 35 minutes and the average depth is 72ft, but the second dive is way more penalizing.
So, if I am not mistaken, if you plan a dive using average depth, most likely your real multilevel dive profile will be more conservative.
Did I get this right?
