When the Bottom Time updated, the TTS decreased by 1 minute but the Stop Time remained the same. Why?
This is similar to the second part of the above question. The pressure balance changed in the tissues with the Stop Time in a “thresh hold” conversion resulting in the above indication. The tissue loadings are computed real time which may result in an apparently added minute on some stops or an apparent indication of an “early release” to the next stop depth. Depending on the dive profile, either of these conditions may or may not appear.
