VPM table mode: Because of the model maths, usage of float data type and so on it may happen that the TTS decreases during ascent and continues calculation of the vpm. To keep the values stable the vpm table mode has been introduces. Instead of continously calculation of the stops the stop time is decreased if the diver is close to a deco stop. If the table is violated (e.g. by not doing gas change) the table will be updated to the new, longer runtime. The table will not be switch back to a shorter version in case e.g. the missed gas change is performed
