From: Linus Torvalds <[email protected]> Date: Sun, 27 Sep 2015 22:26:03 -0400 Subject: [PATCH] Don't use surface sample data for cylinder beginning/end pressure
At the beginning of the dive, let the cylinder cool down if the diver starts off at the surface. And at the end of the dive, there may be surface pressures where the diver has already turned off the air supply (especially for computers like the Uemis Zurich that end up saving quite a bit of samples after the dive has ended). So just don't use surface samples to populate the beginning/ending cylinder pressure data.
